A line system (1) for fluids having volatile components, which comprises at least one fluid line (2,3,4), each having a separate inlet (10) and outlet (11), the fluid lines (2,3,4) being enclosed by a first line wall (12) and extending jointly over a section (A) of the line system (1) close-fitting to one another, but being separated from one another at least by the first line wall (12) over the entire length of the fluid lines (2,3,4). The line system (1) is implemented as a plastic hollow profile at least over the section (A) and comprises a further fluid line (8), which is enclosed by a second line wall (13), and comprises one or more line chambers (8″,8′″), which are at least partially separated from one another by support webs (7), whose totality at least essentially encloses the fluid lines (2,3,4). In addition, the first and second line walls (12,13) and the support webs (7) of the plastic hollow profile being implemented from the same polymer material. The line system (1) according to the present invention is characterized in that the further fluid line (8) is implemented as a scavenging line (8) having scavenging chambers (8″,8′″) and is connected to a scavenging device, which is implemented for flushing or suctioning the scavenging line (8) and therefore for conveying away and collecting permeates originating from the fluid lines.

A pet shelter includes a bottom member having an edge, a top member having an edge, and a medial member disposed between the top and bottom members. The medial member has a top edge and a bottom edge. The pet shelter includes a lock for selectively interconnecting the bottom member to the bottom edge of the medial member and a lock for selectively interconnecting the top member to the top edge of the medial member. The lock includes a tab disposed in the bottom edge of the medial member and a tab disposed in the edge of the top member. The bottom member includes an aperture for receiving the medial member tab to thereby selectively lock the bottom member to the medial member. The medial member includes an aperture for receiving the top member tab to thereby selectively lock the top member to the medial member.

Vanes positioned immediately adjacent the swept area of a moving friction brake rotor induce a flow of air over the rotor by displacing the boundary layer of gases from the rotor surface and conducting such layer along the intercepting surface of the vane, and thus inducing a flow of cooler air over the rotor. Under heavy braking, friction pad particles and substantial quantities of thermal energy in the superheated gases of the boundary layer are removed by the vanes.

An inlet, positioned to access the flow of air passing around and under a moving vehicle, may draw in air which is conveyed through a duct and discharged to cool a brake on a vehicle. The inlet has a closure. The closure is opened and closed on demand by a temperature-operated actuator incorporating an active or smart material under the direction of a controller. In embodiments, a sensor, suitably positioned to sense a temperature representative of the brake temperature, communicates the sensed brake temperature to the controller. The controller may respond to the sensed brake temperature, by triggering operation of the actuator. Typically the closure is opened to allow passage of cooling air to the brake when the sensed brake temperature exceeds, or is anticipated to exceed, a predetermined temperature.

One embodiment of a brake drum includes a cylindrical main body portion, a brake drum mounting flange portion, a brake drum transition portion, the brake drum transition portion extending between the cylindrical main body portion and the mounting flange portion, the transition portion having a plurality of vent openings, and one air scoop secured at each of the vent openings, whereby rotation of the brake drum and air scoop induces air movement within a brake drum cavity defined by the main body portion. Each air scoop defines a louver opening which faces the angular direction of drum rotation, an air channel in fluid communication with the louver opening and the brake drum cavity, and a deflection surface located in the air channel. The deflection surface is positioned to re-direct air movement entering the louver opening at an angular direction, to a generally radial and inboard direction.

A floating type disc brake “A” used for a vehicle such as a motorcycle comprising a braking rotor 1A and a hub 2A arranged inside the braking rotor 1A, the braking rotor 1A including an annular rotor portion 11 and a plurality of projections 13A extending radially inward from the inner circumferential portion of the rotor portion 11, and further comprising a connecting means 3 for connecting the braking rotor 1A and the hub 2A at positions in which the projections 13A of the braking rotor 1A are abutted to the outer circumferential portion of the hub 2A. At least one of the rotor portion 11 and the projections 13A is formed with cutout portions 13b at the boundary region between the rotor portion 11 and the projections 13A. It is possible to suppress a local heat dissipation in regions of the rotor portion 11 in which the projections 13A are formed and thus to reduce irregularity of heat distribution in the rotor portion 11 during braking operations.

The invention relates to a brake actuator, especially for a rail vehicle brake, comprising an accumulation brake unit having an energy accumulator for storing and supplying energy for applying the brake, preferably in the event of safety braking and / or park braking, and a locking device for locking and unlocking the energy accumulator. After the release of the locking device, an inertia weight from part of the energy released from the energy accumulator can be subjected to a rotational movement for damping purposes.
