  • Service vehicle with dispensing system
    Patent number: 4911330
    Abstract: A service vehicle includes a frame (10) on which a material dispensing system is mounted. The dispensing system includes reservoirs (30, 32) and (34) for various lubricants or the like and pumps (46) for pumping material out of the associated reservoirs (30, 32) and (34). The pumps (46) are driven by hydraulic motors (50) which may receive hydraulic fluid under pressure through electrically operated control valves (76) from a pressure compensated, variable displacement pump (60) driven by the engine (64) for the vehicle. The use of the pressure compensated variable displacement pump (60) achieves operating efficiencies.
