ABSTRACT:
A hydraulic motor having a housing and a shaft journaled for rotation along the longitudinal axis of the housing. The shaft carries an eccentric on which is rotatably mounted a bearing block. The housing has a plurality of hydraulic cylinders grouped about the axis of the shaft in a common plane normal to the axis of rotation of the shaft with each cylinder having a hollow piston displaceable therein and biased in a direction toward the bearing block. The shaft and the eccentric have inlet and outlet passages communicating with the bearing block and adapted to communicate a source of hydraulic fluid pressure and an exhaust means respectively therewith. Means are provided on the eccentric for separating these passages from one another with the bearing block having a port communicating fluid from the aforementioned passages to the piston interior, whereby fluid pressure may be admitted to the cylinders in turn, one after another, during the operation of the motor to exert a direct thrust on the eccentric. Fluid communicated from the interior of the piston acts against the upper ends of the piston on an effective pressure responsive area which is isolatable from the source of fluid pressure such that upon the operation of selected valve means the effective pressure responsive area of the piston may be isolated to positively lock the piston in position and prevent rotation of the shaft.
