Abstract

The hydraulic distributor is fitted with a casing bored to take a floating piston and spring loaded ball valves and seats. The ends of the valve each have a plug closed by a sealing ring and a cover plate carrying a control lever. An upper piston carries a pilot valve fitted with a return spring. Each ball valve has a triangular needle valve and a ball guide. A return spring is fitted to the valve and a spring pressure adjusting screw is mounted behind the spring.
