Abstract
A regulating valve for controlling the flow of fluid from a source to a fluid operated clutch and brake as well as auxiliary devices is disclosed herein. The regulating valve incorporates a hydraulic detent which locks the valve spool in a clutch engaged position in response to the pressurized fluid delivered to the clutch so that the clutch is automatically released when a loss of hydraulic pressure occurs.
