Lifting piston unit has working mechanism that controls especially gas exchange to control openings so further piston in further cylinder is subjected to gas without pistons coming into direct contact

摘要

The unit has at least one cylinder (1a,1b) with a piston (2a,2b) arranged to move in it, at least one connecting rod (3a,3b) and crankshaft (4a,4b). A working mechanism controls the process for a medium, especially a gas exchange, so that by exposing and closing openings are controlled so that a further piston in a further cylinder can be subjected to the medium without the pistons coming into direct contact from the process technology viewpoint.
