A low pressure gear pump and wear plate is disclosed. The wear plate may comprise a sidewall, a drive portion, a driven portion, and a transition portion. The sidewall is free of a sealing member or a recess configured to receive the sealing member. The drive portion includes a drive inlet lip, a drive outlet lip, a drive recessed trough and a drive bore. The drive bore is configured to receive the drive shaft of the gear pump. The driven portion may that include a driven inlet lip, a driven outlet lip, a driven recessed trough, and a driven bore. The driven bore is configured to receive the driven shaft of the gear pump. The transition portion may include a transition aperture configured to receive a first fastener configured to mount the wear plate to the gear housing. The wear plate is made of bronze, aluminum or non-magnetic material.

A liquid pump of the present disclosure includes a container, a shaft, a bearing, a pump mechanism, a storage space, and a liquid supply passage. The shaft is disposed in the container. The bearing supports the shaft. The pump mechanism pumps a liquid by rotation of the shaft. The storage space is defined in the container at a position outside the pump mechanism. The storage space stores the liquid to be taken into the pump mechanism or the liquid to be discharged to outside of the container after being expelled from the pump mechanism. The liquid supply passage is a flow path including an inlet open to the storage space and supplying the liquid stored in the storage space to the bearing.

A screw spindle pump having a spindle housing in which a drive spindle and at least one running spindle meshing therewith are received in spindle bores, and an external housing which accommodates the spindle housing, an axial inlet connection and a radial outlet connection being provided on the external housing. The spindle housing has an axial fluid outlet for the fluid conveyed via the drive spindle and the running spindle through the spindle housing, as well as a drive motor having a drive shaft which runs through a bore in a housing wall, which axially closes the interior of the external housing, io and which is coupled to the drive spindle. A part of the fluid flowing out of the fluid outlet of the spindle housing flows through the seal-free bore along the drive shaft into the drive motor, cools this drive motor and flows back into the external housing.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.

An adjustable vane pump, in particular an oil pressure pump, with a suction side and a pressure side, with a housing and with a rotor, which is supported in the housing so as to be rotatable about a rotor axis and carries at least one vane supported movably in a radial direction, wherein the housing comprises a housing floor and a housing cover transversely to the rotor axis, and wherein an adjustment cage that is arranged between the housing floor and the housing cover, encloses the rotor and the vane and is adjustable transversely to the rotor axis is provided in the housing, wherein the housing and the adjustment cage delimit a pressure chamber fluidically connected to the pressure side, wherein a restoring element is provided, which pushes the adjustment cage into a base end position, and wherein the adjustment cage is deflected from the base end position when a limit operating variable is exceeded in the pressure chamber.

A gerotor pump having an inner rotor and an outer rotor, which is also the rotor of an electric drive, having a housing and a flange which closes the housing with the motor compartment, the rotor being arranged on a shaft and sealing against the flange at a gap, wherein, in addition to the gap, there is at least one device with which at least a partial pressure compensation takes place between the suction region of the gerotor pump and the motor compartment of the gerotor pump.

This invention relates to a waterborne fluoropolymer composition useful for the fabrication of Li-ion-Battery (LIB) electrodes. The fluoropolymer composition contains an organic carbonate compound, which is more environmentally friendly than other fugitive adhesion promoters currently used in waterborne fluoropolymer binders. An especially useful organic carbonate compound is ethylene carbonate (EC) and vinylene carbonate (VC), which are solids at room temperature, and other carbonates which are liquid at room temperature such as propylene carbonate, methyl carbonate and ethyl carbonate. The composition of the invention is low cost, environmentally friendly, safer, and has enhanced performance compared to current compositions.

A scroll-type fluid machine reduces intrusion of abrasion powders, generated by sliding of a conductor causing an orbiting scroll side and a fixed scroll side to be conducted, into a compression chamber, and improves reliability of a compressor. The scroll-type machine includes a casing, a fixed scroll having a flange surface attached to the casing, and a wrap portion provided at an end plate, an orbiting scroll having a wrap portion provided at the end plate, and provided in an opposed relationship with the fixed scroll, a drive shaft connected through a crank portion to the orbiting scroll, an orbiting bearing, a face seal portion arranged between the orbiting scroll and the fixed scroll, a cooling fan, and an orbiting scroll side conductive brush.

A housing for a rotary vane pump includes a suction flange and a discharge flange having a multi-angular cross-section with at least two sides extending parallel to each other, cooling ribs provided on an outer surface of the housing, with the number of cooling ribs in the region with a high internal pressure being greater than a number of cooling ribs in the region with a low internal pressure, inlet and outlet, with the inlet cross-section being greater than the outlet cross-section, and connection elements provided on the housing and each having two installation surfaces connected by a connection surface.
