  • Valve containing coupled, rotatable elements to control fluid flow therethrough
    Patent number: 5275205
    Abstract: In a piezoelectric valve the actual control member (7) is formed by a displacer fluid motor (9) though which the fluid stream (5) flows. A piezoelectric actuating element (8) is disposed in the region of a displacer element (1), which can be moved by the fluid stream (5) and belongs to this fluid motor (9), and acts exploiting the inverse piezo effect during electric actuation to at least indirectly block or release this displacer element (1). The fluid motor (9) is formed preferably by a rotating piston machine, such as a gear pump.

  • Hydraulic cylinder/piston mechanism
    Patent number: 5235896
    Abstract: In a position independent locking of a hydraulic cylinder/piston mechanism, a pressure limiting member is provided in the supply pipe for the hydraulic medium, with the pressure limiting member being open during the hydraulic displacement of the piston and is closed during lack of hydraulic pressure. The pressure limiting member opens starting from a specific pressurization of the hydraulic medium as a result of a force generated by means of the piston and is located in a related working chamber.

  • Damping mechanism for cylinder/piston mechanism
    Patent number: 5213024
    Abstract: A damping mechanism for decelerating the movement of a piston of a cylinder/piston mechanism includes at least one elastically deformable damping element, which in the installed state is disposed undetachably between two holding regions which are spaced apart in the direction of the piston movement and wherein one holding region communicates with the cylinder and the other holding region communicates with the piston during deceleration.
