Title: Hydraulic priority control valve with pressure limitation - has additional outlet to pressure relief valve to avoid excessive pressure in-line to priority user
Inventor: BUETTNER PETER
IPC: F15B13/02
Filed: 1990-08-24
Abstract: Priority control valves are used to apportions the supply of pressurised oil from a common pump to priority and non-priority users.
