ABSTRACT:
A rotary valve coupled to a radial cylinder motor sequentially provides pressure fluid to the cylinders of the motor and drains the cylinders through discharge openings in the valve casing. The rotary distributor of the valve and the valve casing have each two radial face portions directed in opposite axial directions and defining two throttling gaps connected by a chamber in the casing and respectively communicating with intake and return openings in the casing so that a pressure intermediate the intake and return pressures of a fluid prevails in the chamber and axially biases the distributor outward of the chamber while the substantially full hydraulic fluid pressure biases the distributor inward of the chamber. Recesses in the distributor alternatively connect discharge openings with the intake opening and the return opening of the valve casing. The distributor floats axially in the valve casing under the opposed biasing pressures.
