Patent DE-3912278-A1 (DE)
Title: Angle valve
Inventor: GOECKLER FRANZ-JOSEF
IPC: F16K5/04
Filed: 1989-04-14
Abstract: In a known angle valve, the valve element is designed as a hollow-cylindrical piston which is adjusted by a knob arranged externally on the housing. The object of the invention is to design the angle valve in such a way that there is no need for a snap ring to fix the piston in the axial direction and that it is essentially the piston itself which ensures sealing. The piston (51) is composed of a rubber-like plastic which rests by means of its continuous end wall (53) against an inner shoulder (41) formed on the downstream side in the wall (45) of the housing (1) adjacent to the knob (6). Use of the angle valve as a quick-closing angle valve. <IMAGE>
