Abstract
1,264,446. Adjustable dashpots; valves. G. KROMSCHRODER A.G. 1 Dec., 1970 [9 Dec., 1969], No. 57012/70. Headings F2S and F2V. The opening movement of an electromagnetically operated valve (Fig. 1, not shown) is retarded to an adjustable extent by an hydraulic dashpot 1 having a movable end wall 28 limited in its movement by an abutment member 23 which is adjustable with respect to the dashpot housing 8. Until the movable end wall abuts the member 23 the movement of the working piston 15 is substantially unimpeded. The point in the stroke at which damping begins can therefore be varied by adjusting the position of the abutment member 23 on the housing 8. The movable end wall may be constituted by a diaphragm (14, Fig. 2, not shown), or a rolling diaphragm instead of a floating piston. A bellows 20 is provided to absorb any vacuum created behind the working piston 15.
