ABSTRACT:
A reversible motor includes a rectilinear shaft (1) having peripherally arranged semi-spherical cavities (24) each engaging the ball-appendage (25) of a radial cylinder (21). A related piston (28) reciprocates axially within each cylinder chamber (27) and is also furnished with a ball-appendage (29) connected within a spherical socket (30) located in a traverse (31). The traverse joins two discs (32 and 33) together whose inner cylindrical surfaces rotatably surround a pair of stationary eccentric rings (38) rotatably engaging the shaft (1). The shaft rotates by means of a drive hub connected to the actual shaft and having arms (42) in contact with a recess (43) formed in the rotating discs (33). A roller wheel (45) protruding laterally from each of the radial arms into the recess (43) transmits rotation to the drive hub. In the case of a motor with variable cubic capacity, provision is made for a pair of arms (49) with upper extremities connected to a traverse (57 ) and provided with a hub (50) coupling outwardly in rotation with the relative internal cylindrical surface of the discs (32 and/or 33). The internal surface of each hub is prismatic and coupled--with a degree of clearance--to a like prismatic outer surface of a corresponding fixed bush (52) whose inner surface couples in rotation with the shaft (1). The traverse (57) is adjustable in height in order to vary c.c. Fluid distribution is accomplished through the motor shaft.
