A spray nozzle assembly for a steam desuperheating or attemperator device. In one embodiment, the spray nozzle sub-assembly of the spray nozzle assembly comprises a fixed nozzle element which is integrated into a spring-loaded nozzle element, and is specifically adapted to improve water droplet fractionation at higher flow rates while further providing an effectively higher spray area through the formation of two water cones (rather than a single water cone), such water cones being sprayed into a flow of superheated steam in order to reduce the temperature of the steam. In another embodiment, the spray nozzle sub-assembly of the spray nozzle assembly comprises a nested pair of spring-loaded primary and secondary nozzle elements which are also adapted to provide an effectively higher spray area through the formation of two water cones.

A caliper brake system includes a housing, a bore within the housing, and a piston slidably positioned within the bore. The brake system also includes a spring assembly, a fluid chamber defined by the bore and the piston, and a hydraulic fluid supply network. The spring assembly provides a biasing force to maintain the piston in an actuated position engaging a stator which engages the rotor of a vehicle. The hydraulic fluid supply network provides pressurized fluid to the fluid chamber to selectively overcome the biasing force of the spring assembly and move the piston to an unactuated position to release the rotor. Thus, the caliper brake is spring actuated and hydraulically released.

A coupling mechanism couples the valve shaft to an electric actuator shaft and allows the flapper valve to move to the open position in response to exhaust flow sufficient to overcome a biasing force of the resilient member without requiring input from the electric actuator.

The invention relates to an ice dispenser (10) for a refrigerator that includes a flap unit (24) which is arranged in an ice dispenser shaft and which can be adjusted between a release position which releases the ice dispenser shaft for dispensing ice and a locking position which blocks the ice dispenser shaft against dispensing ice, a pulse-controlled actuating magnet arrangement (58) for actuating the flap unit (24), and mechanical retention means (36, 64, 66) which releasably retain the flap unit (24) in the release position and in the locking position thereof, respectively.

A check valve for pick-and-place applications includes a valve housing with a chamber, and a chamber shuttle with a cavity. The chamber shuttle is accessible from outside the chamber and adapted to receive a suction head. The chamber shuttle is adapted to travel within the chamber and establish “valve-open” and “valve-closed” states based upon the contact of the suction head upon the work piece surface. Blow off of the work piece surface is allowed by a fluid flow channel interposed between the suction head and the chamber shuttle cavity.

A method and system for producing hollow rib structures for trim components and panels using gas assisted injection molding. Spring biased movable insert members are provided in the mold cavity, particularly at the ends of the structural rib members. After the plastic material is injected into the mold cavity, gas is introduced into the rib members in order to provide hollow channels therein. The displaced resin material forces the insert members to the full cavity positions and completes the formation of the molded plastic article.

A window handle is configured to be manually snapped onto a driveshaft of a window actuator of a window. A locking structure securely attaches the handle to the driveshaft to prevent the handle from being pulled off of the driveshaft. The window handle is a folding handle that includes an arm that pivots relative to a base between closed and operable positions. A detent mechanism releasably holds the arm in its open position. A compression spring provides operational biasing force to both the detent mechanism and the locking structure. The arm and base include mating protrusions and bores that fit together to define a pivotal connection between the arm and the base.

A double acting dual stroke fluid pump with pressure assists is disclosed. First and second pistons are mounted to a common shaft which reciprocates within first and second cavities during compression and suction strokes. The second piston may have a one way valve which opens and closes during the compression and suction strokes to enable the fluid pump to force fluid out of the outlet during both the compression and suction strokes.

An improved spray nozzle assembly for use in a steam desuperheating device that is adapted to spray cooling water into a flow of superheated steam. The nozzle assembly is of simple construction with relatively few components, and thus requires a minimal amount of maintenance. In addition, the nozzle assembly is specifically configured to, among other things, prevent thermal shock to prescribed internal structural components thereof, to prevent “sticking” of a valve element thereof, and to create a substantially uniformly distributed spray of cooling water for spraying into a flow of superheated steam in order to reduce the temperature of the steam.

A compressed gas regulator preferably includes a body having a piston chamber and an output port. A regulator piston can be arranged in the piston chamber with a first surface being acted upon by pressurized gas having the output pressure. A second surface of the piston can be acted upon by a biasing member, such as a spring or spring pack. The biasing member supplies a biasing force that urges the piston toward a first position. The output pressure of the pressurized gas acting on the first surface creates a force that urges the piston toward a second position. A piston seal is preferably arranged on an end of the piston stem to seat against and seal off an inlet port when the piston is in the second position. A pressure adjustment member can be configured to adjust the amount of biasing force applied by the biasing member on the second piston surface. A plug can provide the inlet port, with a stop ring retaining the plug in place to prevent over-pressurization. For CO2 applications, the compressed gas regulator can also include an expansion chamber and a bleed valve. A swivel connector can surround an end of the pressure adjustment member and connect to a source of compressed gas.

A release valve for connection to an inflatable cushion comprising an air conduit, a fitting at a first end of the air conduit for insertion into an air tube in fluid communication with the interior of the cushion, and an air inlet port at the opposite end of the air conduit and a filter assembly at the air inlet port. There is first, vertically orientated, spring biased ball valve centrally positioned in the air conduit including at least one air egress vent and being operatively associated with a spring biased actuator in the ball valve housing for opening the first ball valve. The button and first ball valve define a gap to minimize accidental air release. A second longitudinally orientated, spring biased ball valve is positioned in the air conduit adjacent the air inlet port.

A bit retaining system for a rotary tool or device such as a router is disclosed. The bit retaining system may include a collet assembly and a control assembly.

A double acting dual stroke fluid pump with pressure assists is disclosed. First and second pistons are mounted to a common shaft which reciprocates during compression and suction strokes. During each of the strokes, fluid is pumped out at an outlet. This is accomplished by way of a one-way valve on the second piston. The one-way valve is opened or closed depending on whether the first and second pistons are in the compression or suction strokes. Additionally, pressure from the outlet assists in traversing the first and second pistons in the compression stroke. During the suction stroke, the fluid pressure applies a force on the first piston to counteract the fluid pressure on the second piston so that a smaller spring may be used. The size requirements of the solenoid and spring are reduced. Additionally, the fluid pump provides lower pressure spikes compared to prior art fluid pumps since fluid is pumped out during both the compression and suction strokes and also provides a more even flow of fluid out of the fluid pump.
