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: 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.
