摘要： Input torque, at a comparatively low energy level and preferably delivered constantly, is converted to comparatively high energy output torque pulses by storing the applied torque in a leaf spring which, in its unstressed state, is elastically deformed. Energy is accumulated in the spring by twisting it about its longitudinal axis through rotating a first end thereof. Stored energy is released by periodically allowing the second end of the spring to rotate.

摘要： Systems for delivering fluid at substantially constant pressure to consuming loads which exhibit widely varying demands. The systems employ parallel connected booster pumps which may be operated in either of two rotational directions to provide two output flow rates for each pump.

摘要： A pressure limiting device for protecting a fluid pressure circuit involves a stack of elastomeric washers, and each of the washers has a slit through which fluid can bleed to reduce the fluid pressure below a critical value; the slits are normally closed and so prevent substantial fluid flow, but are able to open to pass fluid when the pressure reaches a critical value at which the pressure distorts the stack of washers.
摘要翻译： 用于保护流体压力回路的压力限制装置包括一堆弹性垫圈，并且每个垫圈具有狭缝，流体可以流过该狭缝，以将流体压力降低到临界值以下; 狭缝通常是关闭的，因此防止实质的流体流动，但是当压力达到压力使堆叠垫圈变形的临界值时，能够打开流体。
