16806 results about "Throttle" patented technology

A throttle is the mechanism by which fluid flow is managed by constriction or obstruction. An engine's power can be increased or decreased by the restriction of inlet gases (by the use of a throttle), but usually decreased. The term throttle has come to refer, informally, to any mechanism by which the power or speed of an engine is regulated, such as a car's accelerator pedal. What is often termed a throttle (in an aviation context) is also called a thrust lever, particularly for jet engine powered aircraft. For a steam locomotive, the valve which controls the steam is known as the regulator.

Pile driving control apparatus and pile driving system

A pile driving control apparatus for a pile driving system includes a hydraulic control system that controls a throttle of a pile driving hammer, and thereby controls an impact velocity of the hammer with a pile. A controller provides a control signal to the hydraulic control system. Based on the control signal, the hydraulic control system controls an impact velocity of the hammer during a subsequent hammer stroke. The controller may determine one or more control parameters such as sound pressure at a sound control location during a hammer stroke, vibration at a vibration control location during a hammer stroke, an impact force imparted to the pile during a hammer stroke, and / or actual pile capacity of the pile, and provide to the hydraulic control system a control signal based on the determined control parameter(s).

Methods and apparatus for cycle time improvements for atomic layer deposition

Different periods of an ALD cycle are performed using different purge flows and, in some cases, different pumping capacities, while maintaining the reactor chamber at a nominally constant pressure. The purge flows may, in some cases, utilize different gasses and / or may be provided through different flow paths. These operations provide for ALD cycle time improvements and economical operation with respect to consumables usage. In some embodiments the use of an annular throttle valve provides a means for controlling downstream flow limiting conductances in a gas flow path from the reactor chamber.

Expansion valve with refrigerant flow dividing structure and refrigeration unit utilizing the same

An expansion valve of the present invention has a structure which integrates a refrigerant flow divider. The expansion valve includes a refrigerant flow dividing chamber 6 on the downstream side of a first throttle 10. Flow dividing tubes 12 are connected to the refrigerant flow dividing chamber 6. In the expansion valve, refrigerant which has passed through the first throttle 10 is sprayed into the refrigerant flow dividing chamber 6, so that the flow dividing characteristic of the refrigerant is improved. Also, due to an enlargement of the passage in the refrigerant flow dividing chamber 6, the ejection energy of a flow of the refrigerant ejected from the first throttle 10 is dispersed, whereby a discontinuous refrigerant flow noise is reduced.

System and method for utilizing informed throttling to guarantee quality of service to I/O streams

The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read / write accesses (I / Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I / O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I / O streams is used to apply controls to guarantee quality of service to all I / O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I / O stream is created that will always be applied to that I / O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I / O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.
