Abstract:
A rotary actuator incorporating an enclosure with a rectilineal slideway along which a slide member is movable has means at one end of the slide member for moving the member along the slideway and further means at the other end of the slide member for restraining the slide member from rotary movement; the slide member carries a screw threaded nut assembly which engages a worm screw forming a part of an output shaft which is rotated when the slide member slides.
Abstract:
A mechanism comprises a diaphragm and a cam in which a rotary output shaft is continuously oriented at an angular position which is a predetermined function of the pressure or pressures of one or more fluids supplied to the mechanism. The cam is enclosed by a stationary sleeve and prevented from axial movement relative the sleeve by spherical members operatively connecting the cam to the sleeve.
Abstract:
Manually operated single or multiple fluid motors for generating fluid pressure and driving a reciprocating servo motor having a screw like reciprocating force transmitting element and a rotary power take off member connected to a coupler or transmission for use as an auxiliary or primary drive for various work devices.
