Abstract
The piston (2) extends through an end piece (4) of the cylinder (1), and has inlet apertures (23) in its part outside the cylinder which admit water to the piston hollow chamber (17). In its end inside the cylinder chamber (12), the piston has at least one connecting channel (25) functioning between it and the cylinder chamber during its movement out of the chamber. A check valve (26) prevents overflow of water in the opposite direction during counter-directed piston movement.
