A DEVICE FOR ENERGY TRANSFER

摘要

An apparatus for converting mechanical rotation into pressure energy and/or vice versa, and essentially comprises a piston (1) disposed in a first cylinder (2) and provided with at least one stub shaft (4) which extends radially from the piston (1) through an axial slot (5) in the wall of the first cylinder (2) and which extends through this wall and into a groove (6) inclined in relation to the slot (5) for guiding the stub shaft (4) along a periodic curve, and moreover the cylinder chamber on one side of the piston (1) is connected to an energy source and/or energy recipient, and the cylinder chamber on the other side of the piston (1) is connected to another and/or the same energy source or energy recipient.
