Abstract
A valve assembly used in combination with a pressurized-fluid source having a high-pressure side and a low-pressure side and a load has a pressure-actuated flow regulating valve having a housing and a valve body movable in the housing and defining therein a pump compartment connectable to the high-pressure side of the source and a load compartment connectable to the load. The body is movable between a front position permitting free flow from the pump to the load compartment and a rear position limiting such flow. The valve body is formed with a throughgoing bypass passage having one end open into the load compartment and an opposite end. A spring braced between the valve body and the housing urges the valve body forwardly along an axis toward the load compartment. A relief valve in the housing connected to the opposite bypass passage end and to the low-pressure side of the source relieves pressure in the load compartment when pressure in the load compartment exceeds a predetermined limit.
