  • Device for producing mechanical force by pressure of a fluid
    Patent number: 4638724
    Abstract: In a device for the production of pressure by means of a piston (2), the piston (2) which has a rectangular cross-section is arranged in a cylinder (1) whose cylinder bore has also a rectangular cross-section. A cylindrical sleeve (3) is arranged inside the cylinder (1) and its edges rest tightly against two parallel surfaces (11, 12) located opposite each other. When a pressure agent is led into the interior of the sleeve (3) over a cylinder wall (9), the sleeve (3) pushes the piston (2) with a high pressure out of the cylinder block.

  • Device for the production of pressure
    Patent number: 4543877
    Abstract: A device for exerting pressure comprising a piston and mating cylinder, each having a rectangular cross-section, and an elastic sleeve disposed between the end of the piston and the end of the cylinder. Means are provided to pressurize the elastic sleeve, thus exerting force on the piston, tending to move it.
