<p>The machine has a rotor (11) turning on a stationary hub (10). Radial cylinders (12) in the rotor run in succession over ports, from inlet and discharge passages (13, 14) in the stub. Pistons in the cylinders press with their outer ends on the inside of a stator case (20) which is eccentric to the rotor to produce the reciprocation. The pistons are formed by balls (16) held in cylindrical sleeves (17). The balls provide rolling contact on the stator whilst the sleeves provide surface contact between the piston and cylinder to give a good seal. The radial length (H) of the sleeve is less than the dia. (D) of the ball.</p> |
