Abstract: A system for cooling individual integrated actuator packages (IAPs) positioned throughout the aircraft in a power-by-wire actuation system is disclosed. A low-pressure hydraulic fluid circulates throughout the aircraft to control the temperature of the individual IAPs and to maintain and replenish the hydraulic fluid within the individual IAPs. A thermo-control loop containing low-pressure hydraulic fluid includes a pump, low-pressure hydraulic lines, a heat exchanger, a reservoir and a filter. The entire system provides heat transfer for a high- or low-temperature environment, as may be present on an aircraft. The individual IAPs may be coupled together in series or, alternatively, in parallel, depending upon the design constraints of the system. Compared with distributed hydraulic systems, energy consumption, weight, and cost are significantly reduced by using a low hydraulic pressure for the circulating fluid. Survivability is significantly increased over that provided by a distributed hydraulic system.

Abstract: A hydraulic fluid supply system includes a single motor driven pump which supplies a dual pressure level output for providing both a high pressure oil output and a low pressure oil output. In combination with a turbomachine, the dual pressure level output of the oil pump obviates the requirement of pressure reducing valves in the low pressure supply lines and losses associated therewith. Moreover, since only a portion of the entire oil requirement is raised to the higher pressure level, the pump motor horsepower requirements are reduced to save energy and thereby improve overall system efficiency. A further improvement is a system of pressure differential valves whereby under certain conditions, high pressure oil flow is conserved even though the low pressure oil flow momentarily drops below a preset value.

Abstract: Pressurized oil is delivered into the space between the friction surfaces of a servo-motor actuated disc brake, such delivery being momentary and in response to the delivery of pressurized oil to the servo-motor itself. Such oil into the space serves to modulate the engagement of the friction surfaces, and also to lubricate and cool the same. The arrangement may include a cylinder having a movable member responsive on one side to the pressurized oil going to the servo-motor for pushing oil via a maximum pressure valve to the said spaces. The brake may be a control for the guide member of a double rotation torque converter.

Abstract: A cooling system for a lift truck which includes a hydrostatic cooling fan mounted within a duct portion of the counterweight rearwardly of the engine and radiator to draw engine heat through the radiator and dissipate it from the rear of the truck. In one embodiment the fan motor is driven by a fixed displacement pump and is connected in series with other hydraulic accessories. A thermo-modulated pressure relief valve connected in parallel with the fan motor varies the differential pressure across the fan motor and thus fan speed in response to changes in temperature of transmission oil and largely independently of system pressures and engine speed. In a second embodiment a hydraulic fan motor is driven by a variable pressure compensated, variable displacement pump. The motor is connected in series with a thermo-modulated pressure-reducing valve and in parallel with other hydraulic accessories of the lift truck to vary fan speed with variations in engine temperature and independently of variations in system pressures and engine speed.
