Abstract (en)

[origin: EP2436919A1] The pump has axial pistons supporting against a swash plate whose inclination is controlled by two antagonistic cylinders. A port plate includes a suction port (22) and a discharge port (23) to ensure the distribution of the pump. The plate includes compression and decompression semi-whiskers (25, 26) between ends of the ports, where the dimension of the semi-whiskers are determined such that the decompression semi-whiskers do not communicate with the suction port and the compression semi-whiskers do not communicate with the suction port. A groove is arranged between the ends of the ports.
