The invention relates to a pressure oil filter system for a hydraulic transmission, in particular for a motor vehicle transmission, comprising at least one oil pump which can be actuated as required and which has a pressure side and a suction side, a pressure line to a consumer and at least a first oil filter which is arranged at the pressure side of the oil pump in the pressure line, wherein means for damping pressure surges during intermittent operation of the oil pump are provided in the pressure line upstream of the first oil filter in the flow direction of the oil.

A planetary gearbox of a gas turbine engine has a planet gear which, via a bearing, is arranged rotatably on a planet pin of a rotatable planet carrier. Oil is introduced through an opening, arranged radially within the bearing, into an oil feed which is open at a feed side and which is connected to the bearing and rotationally joined to the carrier. As the carrier rotates, the oil downstream of the opening is conducted toward the bearing unit by centrifugal force. The open oil feed is, between the opening and the bearing, configured an oil filter through which the oil is conducted. The filter extends counter to the flow direction of the oil from the opening in the direction of the bearing unit, in a flow direction of the oil in the open oil feed.

A hydrostatic transmission subassembly for a vehicle includes an adapter manifold and a hydraulic pump mounted to the adapter manifold. The pump includes a pump housing and a pump porting manifold including pump porting for communicating fluid to and from the pump. The adapter manifold may include a mounting section adapted for mounting to the vehicle and a fluid interface section extending from the mounting section. The fluid interface section includes a pump interface having pump interface porting, in which the pump interface engages with the pump porting manifold to fluidly connect the pump interface porting with the pump porting. When the mounting manifold is mounted to the vehicle via the mounting section, the mounting manifold supports the hydraulic pump. The fluid interface section also includes a motor interface having motor interface porting for fluidly connecting to a motor, which enables the mounting manifold to fluidly connect the pump and motor.

Flow control elements (FCEs) and fluid apparatus including the same are described. In embodiments the flow control elements (FCE) include a body that includes a front side, a back side, a left side, and a right side. The body further includes a base region, an upper region, and an intermediate region between the base region and the upper region. The FCE is configured to move in response to a fluid flow (or, more specifically, a pressure differential across the FCE) to regulate a flow of fluid past the FCE. In embodiments the FCE is included in a fluid apparatus for a vehicle, such as but not limited to a suction filter for a vehicle transmission.

A powertrain assembly includes one or several electric motors, a gearbox comprising a gearbox housing, an axle comprising: an axle housing, movable parts inside axle housing, comprising a shaft for a wheel, a lubricating system comprising an axle lubricating device comprising an axle oil sump and a gearbox lubricating device comprising a gearbox oil sump inside the gearbox housing which is a dry sump having an oil storage area which is separate from said gearbox oil sump, a scavenge pump and a first duct configured to retrieve oil from gear box oil sump and to convey the retrieved oil up to the oil storage area, and a main pump and a second duct configured to convey oil from the storage oil area to lubricate the gears of the gearbox.

A rotating electrical machine and an input member are placed on a first axis, a counter gear mechanism is placed on a second axis, and a differential gear mechanism is placed on a third axis. The input member, the counter gear mechanism, and the differential gear mechanism have portions placed on an axial first side with respect to the rotating electrical machine. A pump portion is placed on the opposite side of an imaginary plane passing through the first axis and the third axis from the second axis, and is placed at a location that overlaps at least one of the rotating electrical machine and the differential gear mechanism in an axial view. The pump portion is placed on the axial first side with respect to the rotating electrical machine.

A bypass apparatus for lubricant in an unregulated pressurized gearbox including: a block including a lubricant inlet in fluid communication with a pressure relief valve, wherein the pressure relief valve diverts lubricant into the gearbox or into an oil filter, wherein lubricant is returned to the gearbox when the lubricant is cold and/or pressure at the pressure relief valve is high to reduce damage to the gearbox caused by high pressure during a cold start, and when the lubricant temperature increases and the pressure is reduced the pressure relief valve closes and lubricant enters the oil filter.

The oil content of at least two kinematic modules in different axes of the industrial robot is connected by the oil line to the closed circuit of the oil between interconnected kinematic modules. The system includes the pump engaged in pushing the oil in the upper-mounted kinematic module and the filtration device for filtering the oil in the circulating circuit or in a separate circuit with the oil tank. The system includes at least one diagnostic element, for example an oil temperature sensor or an oil pressure sensor or an oil pollution sensor connected to the evaluation unit. The evaluation unit is interconnected with the industrial robot control system, thus, the oil economy is controlled and planned depending on the actual load of the individual kinematic modules.

A high-capacity fluid pump comprising a dedicated lubrication system in fluid communication with the pump's drive assembly to reduce wear of internal components within the gearbox, as well as a drive shaft-supported impeller and outboard head to reduce deflection. Moreover, the blades of the outboard head are preferably shaped to decrease the inlet's cross section and stabilize incoming fluid, thereby reducing cavitation, pre-rotation, and turbulent flow at the pump inlet and increasing the overall velocity of incoming fluid.

A removable oil filter system includes an oil filter mount, an oil filter element removably connected to the oil filter mount, an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, and a full-bypass indicator in fluid communication with the oil filter mount. The impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system. The full-bypass indicator is capable of reporting a full-bypass condition of the oil filter system.
