Locking valve with valve chamber inside housing - has one inlet, two outlets and elastically deformable closure piece against two valve seatings

摘要

The locking-valve has a valve-chamber (2) inside a metal valve-housing (1) and which has one inlet (4) and two outlets (7,8) and contains an elastically deformable closure piece (3). The closure piece rests against two valve seatings (5,6) joining the valve chamber to the two outlets. The closure-piece, when not exposed to pressure from the inlet, completely fills the valve chamber. The valve seatings and the inlet opening are in the wall of the valve chamber. ADVANTAGE - The locking valve prevents back-flow into the two outlets.
