Abstract

582,263. Rotary motors. SULZER FRERES SOC. ANON. July 12, 1944, No. 13310. Convention date, Aug. 14, 1943. [Class 110 (ii)] [Also in Group XXXIII] A sliding vane rotary motor is used to produce an axial movement on the operating rod 8 of a variable pitch propeller through the thread and nut mechanism 58, 59. To balance the thrust of this rod discs 56, 57 are provided, one of these being exposed to the pressure of the operating liquid in each direction of rod movement.
