Title: Apparatus for rotating and displacing in axial direction a machine element
IPC: B29C45/00
Filed: 1974-12-31
Abstract: An apparatus for selectively moving, for instance alternately or simultaneously rotating and displacing in axial direction, a machine element mounted to be rotatable and axially displaceable, comprising a motor, a hollow cylinder and a piston displaceable in said hollow cylinder. The piston is provided with a connection element for rigidly connecting it with the machine element. The piston also has a lengthwise extending opening which is sealed towards the outside at the side of the connection element and at the other end there extends into said lengthwise extending opening a drive shaft connected with said motor. This drive shaft at the side of the connection element has an end which together with the inner surface of the piston forms a first sealing section forming a sealed sliding seat, said drive shaft at the region of its end connected with the motor possessing a second sealing section which together with the hollow cylinder or an element rigidly connected therewith forms a tightly closing sliding seat. The piston and the drive shaft possess coupling means disposed between both of the sealing sections, said coupling means rigidly rotatably connecting the piston and the drive shaft with one another but permitting axial displacement relative to one another. The drive shaft possesses a throughpassage which connects a first hydraulic connection with an end section of the lengthwise extending opening of the piston, said end section being located at the side of the connection element, and a second hydraulic connection opens into the hollow cylinder between the second sealing section and the end of the piston sliding surface which confronts such second sealing section.
