摘要： A peripheral sealed interlock for a dual diaphragm tandem vacuum booster with front and rear housings is provided. An outer radial peripheral end of a divider of the inventive interlock is greatly simplified and in the preferred embodiment a bead of a secondary diaphragm is allowed to seal on a rear housing member as well as with the periphery of the divider. The interlock provides a simplified design allowing independent compression of primary and secondary diaphragm beads while at the same time providing an interlock which require lower compression for assembly and sealing.

摘要： A power booster assembly, has a dual-durometer reaction disc instead of the disc having a single durometer value throughout. The disc has an outer annular portion of a higher durometer value than the durometer value of the disc inner center portion. The higher durometer value is preferably on the order of 80 durometer and the lower durometer value is preferably on the order of 45 durometer. The outer annular portion transmit part of the reaction force to the booster power wall, and the inner center portion transmit the remainder of the reaction force to the reaction piston and thence to the booster input member. The disc may be made as a unitary part or may be made in two parts with the inner center portion being later inserted into and mechanically interlocked with the outer center portion.
摘要翻译： 功率增压器组件具有双重硬度的反应盘，而不是具有单一硬度值的盘。 盘具有比盘内部中心部分的硬度值更高的硬度计值的外部环形部分。 较高的硬度计值优选为80度的硬度计，较低的硬度计值优选为45度数量级。 外环形部分将反作用力的一部分传递到增压器功率壁，并且内中心部分将反作用力的剩余部分传递到反作用活塞，然后传递到增压器输入构件。 盘可以制成单一部件，或者可以制成两部分，其中内部中心部分稍后插入并与外部中心部分机械地互锁。

摘要： A hydraulic booster in which the booster piston return spring is formed as a tubular conduit to conduct hydraulic supply pressure to a closed center valve. Upon actuation, the valve opens to permit supply pressure to flow into the power chamber and by valving action controls the exhaust of pressure from the power chamber so as to establish the desired actuating pressure therein. The tubular conduit forming the power piston return spring and transporting the supply pressure to the closed center valve permits a shorter overall axial length of the hydraulic booster by accommodating the movement of the supply pressure chamber at the closed center valve. It also permits less charged supply pressure leakage by accommodating a better pressure seal arrangement.

摘要： Mechanism for attaching a high pressure tube to an opening in a housing using a tapered opening into which a high pressure tube is inserted. A fitting has one end positioned about the tube end and is then press fitted not only to the housing on an outer diameter fitting section but also inwardly against the tube end as well as the other fitting end being press fitted to the housing to further secure the fitting to the housing, all of the press fits providing high pressure seals. The fitting other end also provides for prealignment of a fitting cross passage with a housing side passage so that high pressure fluid flowing between the tube and the side passage has minimal directional change in passing from the cross passage to the side passage. The fitting other end is adapted to receive press fitting force in axial alignment with the fitting.
