  • Tapping circuit including a tapping valve for replenishing and/or flushing the casing of a hydraulic motor
    Patent number: 6802182
    Abstract: The tapping circuit forms part of a main fluid circuit which comprises a hydraulic motor having a preferred operating direction and at least two main pipes suitable for communicating with the cylinder block of the motor and constituting respectively, in said preferred operating direction, a feed main pipe and a discharge main pipe. The tapping circuit comprises a single tapping and removal valve connected continuously via a tapping pipe to that one of said main pipes which, in the preferred direction, serves for discharge purposes. This valve serves to replenish the fluid so as to cool it and/or to flush the internal space of the casing of the motor.

  • Drive mechanism for driving displacement members disposed in tandem
    Patent number: 6036611
    Abstract: A drive mechanism (10, 110) for driving first and second displacement members (12, 14, 112, 114) disposed in tandem. The mechanism includes first and second driven sprockets (16, 18; 116, 118) for respective ones of the displacement members, a hydraulic motor (20; 120), and first and second driving sprockets (22, 24; 122, 124) disposed on the casing of the hydraulic motor so as to be rotated thereby. The mechanism also includes first and second chains (26, 28; 126, 128) disposed in a chain case (30; 130), each chain being engaged on a respective driven sprocket and on a respective driving sprocket. The hydraulic motor (20, 120) is a low-speed high-torque motor, having radial cylinders and a rotary casing. The motor is substantially contained in the chain case (30; 130).
