Abstract (en)
[origin: EP0316500A1] A four-way valve controls a piston (15) located in a cylinder (16). A plate (23), having passages (24, 25) which are used and a passage (26) which is not used in Figure 1, is situated between the body (1) of the valve and the cylinder (16). By rotating the plate (23) by 180 DEG , the passage (24) is situated in a non-use position, whilst the passage (26) joins the ducts (19 and 13) so as to connect the space (21) of the cylinder (16) continuously with an exhaust orifice (6). <IMAGE>
