Abstract

Means of sequential operation of controlled units, comprising a piston unit (13) for operating a first controlled unit that is slip-mounted in a cylinder barrel (1) and valve bodies (9, 15, 16, 20, 33) intended for controlling the flow of fluid from the first controlled unit to a second controlled unit for its operation. The first unit's piston unit (13) contains a passage that in order to convey fluid to the second controlled unit passes over part of the piston unit's (13) outer edge, and that the valve bodies (9, 15, 16, 20) contain an axially displaceable moving ring-shaped valve body (9) surrounding the piston unit (13) that opens and closes the said passage depending on the relative position of the piston unit (13) in the cylinder.
