In-line flow regulator for use in hydraulic flow systems is presented using a fixed size orifice which may be manually adjustable by blocking off a part of the orifice to provide an exact rate of flow in the regulated flow direction and which otherwise provides a free flow in the reverse direction.

In-line flow control valve

A cable reel control valve and associated system for controlling the operation of a hydraulic motor unit coupled to a reel mounted on a vehicle, such as a mine car or the like and wherein the reel is adapted to automatically wind electrical cable thereon as the mine car moves toward the point where the cable is connected to the source of power, and to automatically pay-out the cable as the mine car moves away from the electrical cable connection to the source of power. The cable reel control valve includes a pump port, and a motor port to which the motor for rotating the reel is coupled, and includes a pilot pressure operated bypass valve means for automatically sensing the pressure differential across the pump and motor ports and to automatically bypass the pump flow to reservoir when the cable reel is paying out the cable, and when the cable reel stops, and automatically diverts the full pump flow to the reel motor when the cable is being reeled in in response to movement of the vehicle toward the electrical connection to the source of power.
