An on-board inert gas generation system provides first and second compressors in fluid communication with one another. The second compressor includes an inlet and an outlet. The inlet is in fluid communication with the first compressor. The second compressor is the final compressor stage of the system. An air separation module is fluidly connected to the outlet of the second compressor by a passageway. A vent passage is arranged between the outlet and the air separation module for venting fluid between the outlet and air separation module. The vent passage enables the flow from the second compressor to be increased thereby increasing compressor efficiency and increasing the inlet pressure to the air separation module, which enables use of a smaller air separation module.

The invention relates to a machine oil sump strainer. The machine oil sump strainer comprises a lubricating oil channel and an oil inlet and an oil outlet respectively formed in two ends of the lubricating oil channel, and further comprises an oil return boost channel; one end of the oil return boost channel is communicated with the lubricating oil channel; and an oil return port for flowing in returned lubricating oil is formed in the other end of the oil return boost channel. In actual working process, the lubricating oil in the oil return boost channel is merged with the lubricating oil flowing in the lubricating oil channel by the oil inlet, so that the flow and the pressure of the machine oil sump strainer in the oil outlet are effectively increased; and the oil outlet of the machine oil sump strainer is communicated with an inlet of a machine oil pump, the machine oil sump strainer can effectively improve the inlet pressure of the machine oil pump, reduces the power consumption of the machine oil pump, and promotes the fuel economy. The invention further discloses a lubricating system using the machine oil sump strainer and an internal combustion engine with the lubricating system.

A system disconnector for disconnecting an upstream liquid system providing an inlet pressure from a downstream liquid system by a release valve (34) in response to a pressure drop between the systems, includes an upstream backflow preventer (40), a downstream backflow preventer (64) and a release valve body piston (18) arranged between the backflow preventers (40, 64). A pressure difference between the inlet pressure and a middle pressure between the backflow preventers (40,64) counteracts a spring (60) biasing the release valve body in the opening direction, the release valve body (18) having an effective pressurized surface (d) smaller than the surface effective for the inlet pressure. A hollow space (74) defined by the release valve body is connected to the middle pressure (66). A shiftable seat (76) provided in hollow space (74), is movable with respect to the release valve body to a fixed stop (84) upstream of the valve seat (32).

A battery pack and method of cooling a battery pack. In one form, the battery pack is an assembly made up of numerous battery cells arranged within numerous modules. Cooling channels that receive cooling fluid from a ducted supply are placed between adjacent cells or cooling plates within each of the modules. The ducted supply includes beads or related area-increasing undulations that are designed to improve both the stiffness of the ducting as well as the uniformity of the flow rates of individual cooling channels within each of the modules. In one form, the pressure-enhancing beads are placed in an inlet portion of the ducting that is adjacent a forward portion of one or more of the sequentially-encountered modules in order to promote a more equitable distribution of the cooling fluid between the various cooling channels within each of the modules.

A pump includes a housing, a drive shaft, a centrifugal pump portion having an impeller, and a gear pump portion having first and second gears. The impeller and one of the first and second gears are mounted to the drive shaft to drive the centrifugal pump portion and the gear pump portion at the same rotational speed. The gear pump can be a crescent internal gear (CIG) pump. The drive shaft can be rotated by a magnetic drive. The drive shaft can include a longitudinal bore in fluid communication with a cavity in the magnetic drive and with a discharge of the centrifugal pump portion to circulate working fluid through the magnetic drive to cool the drive. An impeller can be coupled to an inlet of the centrifugal pump portion.

A pump and motor assembly (20) includes a centrifugal pump (30), a bent axis hydraulic pump 58, and a wet-type drive motor (228). The motor has a rotor and a stator that are submerged in hydraulic fluid for full lubrication and cooling. A drive shaft 66 is driven by the motor. The centrifugal pump has a rotatable impeller (50) for pumping hydraulic fluid from an inlet (48) to the bent axis hydraulic pump. The centrifugal pump also pumps fluid to the motor for lubrication and cooling. The bent axis hydraulic pump pumps the fluid and discharges the fluid from the system. The centrifugal pump and the bent axis hydraulic pump are rotatable along a common rotational axis R1 that is angled relative to the rotational axis R2 of the drive shaft.

A gas turbine engine arrangement comprising a gas turbine engine and an inlet screen. The gas turbine engine comprises an engine core comprising an inlet having a radial extent extending from an engine longitudinal axis to a first radial position, and a fan duct comprising an inlet having a radial extent extending from the first radial position to a fan casing, the inlet screen comprising an at least part annular porous grid radially extending across at least part of the radial extent of the fan duct inlet, and not extending across any substantial part of the radial extent of the core inlet.

The invention relates to a low-leakage hydraulic pressure reduction compensation circuit for an aircraft nose wheel steering system. The hydraulic sway compensation circuit includes a turning actuator, a pressure sensitive device, an unloading valve, an anti-leakage device, and a compensator; hydraulic flow and hydraulic pressure are stored in the compensator, and the anti-leakage device is arranged at the outlet of the compensator, and the unloading valve The unloading valve is set at the oil return circuit of the aircraft hydraulic system. Under the action of the back pressure generated by the unloading valve, the hydraulic flow enters the compensator through the anti-leakage device, and forms the required hydraulic pressure under the action of the compensator. The pressure sensitive device It is arranged at the left and right chambers of the turning actuator. When the pressure in at least one chamber of the turning actuator exceeds the pressure threshold, the pressure in the chamber controls the opening of the anti-leakage device through the pressure sensitive device, so that the hydraulic pressure in the compensator flow out of the compensator. The hydraulic anti-sway compensating circuit can have the following beneficial technical effects: reducing the leakage of the compensator of the hydraulic anti-swaying circuit and reducing the hydraulic flow required to be stored by the compensator.
