1,025,764. Reciprocating pumps; compressors. REDEN A. B. SOYA. Dec. 4, 1962 [Dec. 14, 1961], No. 45804/62. Headings F1A and F1N. In a rolling-piston machine comprising a rotor 16 centrally mounted on a valve slide 10, formed with working chambers 18 in which roller pistons 22 reciprocate and surrounded by a rotary ring 24 having curved roll races 30 which lock and entrain the pistons, the radius of curvature of each roll race is such that the turning moment generated by the centrifugal force C acting on the corresponding piston compensates for the presssure acting between the piston and the leading or trailing walls of its working chamber during respective acceleration and retardation of the piston relative to the rotary ring 24. Reference has been directed by the Comptroller to Specification 876,546. |
