Abstract: A flow control valve includes a valve body having a substantially cylindrical bore, and a substantially cylindrical valve element received within the cylindrical bore of the valve body to be reciprocatable. The valve body and the valve element define first and second chambers separated by the valve element. The valve body has a circumferential groove surrounding the valve element, and a plurality of radially-extending passage holes communicating with the circumferential groove. The circumferential groove and the passage holes form portions of the second chamber. The valve element has a plurality of radially-extending throttle holes for establishing communication between the circumferential groove and the first chamber. The flow rate of operation oil flowing between the first chamber and the second chamber via the throttle holes is changed through axial movement of the valve element. The passage holes and the throttle holes are circumferentially arranged in such a manner that even when one of the passage holes circumferentially overlaps one of the throttle holes, the remaining passage hole or holes do not circumferentially overlap the remaining throttle hole or holes.

Abstract: A bypass valve for directing fluid flow, where the bypass valve includes a valve body with a notch in at least one end thereof and a spool seated within the valve body. The spool is rotatable within the valve body. One preferred embodiment of the present invention also includes at least one endcap attached to an axial end portion of the spool, where the endcap includes a protrusion extending thereon for preventing relative rotation between the spool and the valve body when the protrusion is positioned within the notch. A further aspect of the present invention relates to a bypass valve with a valve body including a plurality of ports and a generally cylindrical inner periphery, as well as a spool seated within the valve body, where the spool is rotatable and axially translatable within the valve body. The spool further preferably includes a top seal seated upon a seal seating surface, where the top seal acts in one mode to block a service inlet port, without blocking the other ports, or, in another mode, blocks the service inlet port and the service outlet port, without blocking the other ports.
