Abstract

1363609 Rotary positive-displacement machines J A E NELIMARKKA 17 Oct 1972 [1 Nov 1971] 47766/72 Heading F1F In an hydraulic, or pneumatic, torque-motor a piston 5 fixed to an output shaft 3 engages with a seal 6 and can be displaced between screws 8, which to obviate leakage are furnished with caps 9 carrying sealing rings 10. Working-fluid supply and discharge openings A, B are disposed as shown. The seal 6 may be backed by a part 6a of differing hardness.
