Abstract (en)
[origin: EP0839961A1] The piston (10,11,12) is connected with a connecting rod (11), which with its upper end extends through an aperture in a cylinder cover (6) closing the upper end of the shaft pipe (2) and connecting flush with the ground. The movement of the piston is by means of a double-acting, externally controllable pneumatic cylinder (9), which is connected to a controllable compressed air conduit (28,29). The piston is formed as a connecting rod flange (10), at the lower end of which the connecting rod is formed. With the piston moved outwards, the piston connecting rod flange locates in a sealed fashion on the underside of the cylinder cover.
