Abstract

The radial-cylinder fluid pump comprises a rim of radial cylinders arranged in pairs (3) opposed on a same radial axis lying on a perpendicular plane to a driving shaft (7) equipped with a crank (6) connected to pistons (5) in reciprocating motion in the cylinders; the pistons are stiffly connected to a stem (16) contacting the crank by means of a bilateral guide (15) having perpendicular walls to the axis of said cylinders; a crankpin (6) is arranged in bilateral contact with the guide walls by means of a rolling bearing (17); as well as comprising fluid distribution means to the cylinders during suction and delivery associated in a pump casing (25) composed of unidirectional blade valves (13, 18); the pump has, in the simplest embodiment thereof, a pair of radial cylinders (3) formed by liners (4) being pressed in the pump (2) casing (25); each liner has radial through openings (14) of the pumped fluid in connection with suction and delivery ports in the casing; the unidirectional blade valves (13, 18) being arranged next to the pump casing.
