ABSTRACT:
A flow regulation device includes a main regulator connected to the exhaust pipe and delivery pipe of a fluid motor having a valve controlled by the feed pressure to the motor for varying flow permitted from the motor; flow from the valving means passes through a restriction with pressure between the valve and the restriction tending to close the valve. A supplemental valve opens to shunt flow around the restriction following opening of the first valve with the invention being used for the functional control of a winch.
