Patent application number	Title	Published
20110197575	HYDRAULIC TRANSMISSION APPARATUS MAKING QUICK POSITIVE CLUTCHING/DECLUTCHING POSSIBLE - Hydraulic transmission apparatus including a pressurized fluid source and at least one hydraulic motor fed by said pressurized fluid source. The motor has two motor ducts for feed/discharge, and one casing duct. The motor can be operated in assisted mode, in which it generates torque or in unassisted mode in which it does not generate any torque and its pistons are maintained in the retracted position under the effect of the pressure in the casing duct. The apparatus further includes an accumulator suitable for feeding:	08-18-2011
20110197574	HYDRAULIC TRANSMISSION SYSTEM HAVING A MAIN PUMP THAT CAN BE ACTUATED CONTINUOUSLY - A hydraulic transmission system for a vehicle, the system including:	08-18-2011
20090259378	HYDRAULIC ENERGY RECOVERY SYSTEM - A hydraulic valve having firstly a feed port, a discharge port, a low-pressure link port, and a high-pressure link port, which ports are respectively connected to the feed and discharge ducts of a hydraulic motor, to a low-pressure fluid source, and to a high-pressure accumulator, and secondly an auxiliary port. The valve has a slide that can take up a neutral position for connecting together the feed, discharge, and auxiliary ports, an energy recovery position for connecting together respectively the feed and low-pressure ports, and the discharge and high pressure ports, and an energy delivery position for connecting together respectively the feed and high-pressure ports, and the discharge and low-pressure ports. The slide is caused to move from its neutral position to its other positions by control signals and the auxiliary port can be connected to a reservoir or to a clutch fluid source for clutching or declutching the motor.	10-15-2009
