Abstract

1293039 Valves ROBERT BOSCH GmbH 27 Aug 1970 [28 Aug 1969] 41212/70 Addition to 1233328 Heading F2V A valve device as described in the parent Specification includes an unblocking piston 17 having an annular groove 41 and passages 39 so that the flow of control fluid from the passage 38 is shut off by the unblocking piston before the latter reaches its end position adjacent the check valve, while the flow of control fluid through passage 33 rests upon the base 36 of the piston during the entire unblocking movement.
