Oil circulation for farm tractor gearbox and hydraulic ram - has oil supply to base of sump with injector pump driven by return flow pressure

摘要

The circuit and at least one oil consuming unit (2), has the opening of the supply (4) in the gearbox housing (10) arranged in the base of the oil sump (5). This serves the oil level and the suction opening (12) of the oil suction supply (6). An injector pump (8) is driven by the oil return flow, such that the inlet (13) is connected to the oil return supply (7), the pump suction opening (14) is connected to the base of the oil supply tank (3), and the pump outlet (15) is connected to an oil return supply (16). This opens into the gearbox housing. USE/ADVANTAGE - Optimal oil supply for cooling and lubrication of farm tractor gearbox and hydraulic ram.
