ABSTRACT:
Methods and devices for reducing instability in hydraulic systems are disclosed. A flow control device having an output fitting and a spring-biased piston reciprocally movable in a cylinder past a bypass hole is disclosed. The improvement consisting of metering passages formed in a flow control device to provide hydraulic resistance to dampen the piston. Alternatively, disclosed is a flow control piston having a valving sub-assembly which is resiliently biased. The valving sub-assembly is movable to substantially suppress the flow rate ripple by bypassing a dominant portion of the flow rate ripple. Finally, methods for dampening the resonance, creating resistance, as well as bypassing the flow rate ripple are disclosed.
