A liquid pump for providing a supply to a transmission of an electric or hybrid drive module of a motor vehicle, having a pump housing wherein a pump chamber and a pump rotor are arranged, wherein the pump housing has at least one intake opening, wherein a filter plate which covers at least one intake opening is attached to the pump housing.

The invention concerns a method and an apparatus for operating a multi-phase pump which has a suction-side inlet (10) and a discharge-side outlet (20) and which pumps a multi-phase mixture charged with solids, comprising the following steps:

a. pumping a multi-phase mixture into a discharge-side separation chamber (45),

b. separating a gaseous phase from a liquid phase and a solid phase in the separation chamber (45),

c. separating the liquid phase from the solid phase in the separation chamber (45), and

d. supplying a portion of the liquid phase freed from the solid phase to the suction side.

A pump includes a front plate, a gear plate and a rear plate. A drive shaft has a drive gear, an arbor has a driven gear engaged with the drive gear, and first and second bearings are disposed in the gear plate. The first and second bearings receive the drive shaft and the arbor. The rear plate has drain ports adjacent ends of the drive shaft and the arbor. The arbor has an opening such that media that passes between the first bearing and an outer surface of the arbor is directed to the second drain port via the opening. A drain bushing is positioned against the front plate, and includes an opening for the drive shaft. The drain bushing has a chamber and a radial port. When pumped media passes between the first bearing and the drive shaft it is directed to the chamber and out the radial port.

The invention relates to a filling machine and a method for filling a pasty mass, in particular for the production of sausages, with a vane cell pump for conveying the paste mass, a vacuum pump for generating negative pressure in the vane cell pump, where the housing of the vane cell pump comprises an evacuation opening via which the vacuum pump can evacuate the vane cells. The evacuation opening is formed in the cover of the vane cell pump.

A rotor is shown with an asymmetrical structure for a pump, wherein the rotor includes at least one cutting edge and at least one rounded edge, as well as the pump as such including one or more rotor(s). The rotor (1) has a first circular element (4) where a material-moving cavity (5) is provided in the first circular element (4).

A fluid pump includes a motor disposed within an outer housing. The motor includes a stator and a rotor in electromagnetic communication with the stator. Windings are disposed on the stator that receive an electric current for defining the electromagnetic communication. A pump element is attached to the rotor via a drive shaft. The pump element operates with the rotor to deliver a fluid through a hydraulic fluid path. A plurality of sensors measure information related to at least one of the stator, the windings, the rotor, the pump element, the fluid and the hydraulic fluid path. A controller is in communication with the windings for delivering the electric current to the windings. The controller is also in communication with the plurality of sensors for measuring and recording the information and communicating this information to one of an external memory and an external controller.

Provided is a control device for a hydraulic control valve that can increase an efficiency of removing a foreign matter clogged in the hydraulic control valve. A control device controls a hydraulic control valve that controls a pump capacity of a variable displacement oil pump. The hydraulic control valve includes a sleeve and a spool valve that moves in the sleeve, and is configured to change a pump capacity by controlling an oil pressure by moving a spool valve between one end portion and the other end portion in the sleeve. The control device for the hydraulic control valve includes: a drive control unit that controls driving of the spool valve; and a determination unit that determines whether or not clogging of a foreign matter exists between a sleeve and the spool valve, and determines a position of the clogging of the foreign matter in a case where the foreign matter exists between a sleeve and the spool valve, and determines a position of the clogging of a foreign matter in a case where the clogging of a foreign matter exists.
