Abstract: A linear compressor is provided. The linear compressor may include a shell including a discharge outlet, a cylinder provided in the shell to define a compression space for a refrigerant, a frame to fix the cylinder to the shell, a piston reciprocated within the cylinder in an axial direction, a discharge valve disposed on or at one side of the cylinder to selectively discharge the refrigerant compressed in the compression space, a discharge cover coupled to the frame, the discharge cover having at least one chamber to reduce pulsation of the refrigerant discharged through the discharge valve, and a valve spring disposed on the discharge cover to provide a restoring force to the discharge valve. The discharge cover may include a cover body having a discharge hole, through which the refrigerant discharged through the discharge valve may be discharged outside of the discharge cover, and a guide passage defined in the cover body to guide at least a portion of the refrigerant discharged through the discharge valve into the at least one chamber.

Abstract: A flow rate control device for a pump includes a housing, a choke tubular passageway connected between a pump pressure chamber and an output chamber, a spool valve which is slidably provided in the housing, and which has both ends exposed in the pump pressure chamber and the pressure reducing chamber, respectively, the spool valve causing a pressure medium to flow from the pump pressure chamber into the by-pass port as much as the spool valve slides in an axial direction thereof. In the device, the choke tubular passageway is formed in a central shaft member arranged in the housing, and a sleeve member is provided around the central shaft member, the sleeve member being moved, from the pump pressure chamber towards the pressure reducing chamber, with respect to the central shaft member, in such a manner as to change the opening area of the choke tubular passageway.

Abstract: A by-pass solenoid (32) with an integral check valve assembly (36) for by-passing excess pump (16) fluid flow. The integral check valve assembly (36) positioned in a first chamber (120) of a valve sub-assembly (52) allows fluid flow from an inlet (34) to an outlet port (40) in a normal mode of operation. Upon actuation of the solenoid sub-assembly (50), the by-pass solenoid (32) diverts excess fluid flow to a by-pass port (42) for re-circulation during periods when fluid flow demand is low and still maintains a fairly constant system pressure. Check valve assembly (36) prevents re-circulated fluid from directly entering the working hydraulic circuit and maintains system pressure. The present invention advantageously provides a compact integral fluid flow control device for bleeding excess pump flow.
