ABSTRACT:
An opposed piston fluid motor having a pair of angularly related cylinders rigidly joined at adjacent ends in a common plane is mounted above a base with the common plane normal to the base and the cylinders inclined downwardly from the common plane toward the base in the manner of an inverted V. A crankshaft is rotatably supported above the base with its axis parallel to the base and lying in the common plane below the cylinders. A piston is reciprocably mounted in each cylinder, and an expansible working chamber is provided within the cylinders between the pistons. Working fluid is supplied to the working chamber through a fluid port located at the apex of the cylinders under the control of a rotary motor control valve driven by the crankshaft. The crankshaft has a pair of cranks which are displaced 180.degree. apart. Each piston is connected to a different one of the cranks by a piston rod and a connecting rod. The piston rod has one end pivotally connected to the piston by a transverse pivot pin and an outer end which is pivotally connected to one end of the connecting rod by a pivot pin which is supported at one end of an oscillating arm which is pivotally supported from the base.
