Реферат: The pump arrangement has a priming pump (10) via which the pressurized medium is fed to the suction ports of a high pressure pump (60) contg. at least two pump units. A distribution device (50) selectively connects the suction ports to a pressure port of the priming pump. The suction ports are connected to the pressure port via a slot controller (54) in the distribution device.
Work vehicle control arrangement e.g. for wheel loader has pressure reducer to reduce pilot pressure delivered to variable displacement pump, to regulate pump displacement for limiting hydraulic power consumption
