摘要： A radial cylinder hydraulic motor comprises: oscillating hydraulic cylinders (1) driven to oscillate by means of an eccentric crankpin (2) formed on the motor shaft (3), the oscillating cylinder liners (4) being provided with trunnions (5) for oscillation about a parallel axis (C) to the axis (A) of rotation of the motor shaft which are coupled oscillably to the motor crankcase (6); reciprocating pistons (7) within said liners which are provided with a runner (8) for sliding over the outer surface (9) of said eccentric crankpin; and a rotary disk distributor (10, 23) coupled to the motor shaft for synchronized rotation therewith, adapted to place the conduits (12, 13) of the hydraulic circuit in fluid communication with the conduits (14) of the respective cylinders during the delivery and discharge strokes via ports of slanted or through-going configuration; the rotating disk of the distributor formed with a connection/supply means (38, 40) to the passageway between one face (27) and the inner wall of the distributor cover (41) incorporating a seal (28), with pressurized fluid in the area outside the seal; said passageway connection/supply means comprises a depression (38) extending parallel to the passageway; and it presents said passageway connection/supply means comprising at least one hole (40) in communication with one of the slanted configuration ports (24) to the depression.

摘要： A radial cylinder hydraulic motor comprises: oscillating hydraulic cylinders (1) driven to oscillate by means of an eccentric crankpin (2) formed on the motor shaft (3), the oscillating cylinder liners (4) being provided with trunnions (5) for oscillation about a parallel axis (C) to the axis (A) of rotation of the motor shaft which are coupled oscillably to the motor crankcase (6); reciprocating pistons (7) within said liners which are provided with a runner (8) for sliding over the outer surface (9) of said eccentric crankpin; and a rotary disk distributor (10, 23) coupled to the motor shaft for synchronized rotation therewith, adapted to place the conduits (12, 13) of the hydraulic circuit in fluid communication with the conduits (14) of the respective cylinders during the delivery and discharge strokes via ports of slanted or through-going configuration; the rotating disk of the distributor formed with a connection/supply means (38, 40) to the passageway between one face (27) and the inner wall of the distributor cover (41) incorporating a seal (28), with pressurized fluid in the area outside the seal; said passageway connection/supply means comprises a depression (38) extending parallel to the passageway; and it presents said passageway connection/supply means comprising at least one hole (40) in communication with one of the slanted configuration ports (24) to the depression.
