Particular techniques involve a device for wetting multiple threads with a fluid, and a dosing pump which is connected to the wetting means by multiple conveying lines. The dosing pump has multiple conveying means for generating multiple dosing flows of the fluid and has multiple pump outlets, to which the delivery lines are connected. The conveying means are formed by at least one planetary gear set arranged between housing plates. To achieve, as far as possible, a uniform throughflow without a significant dead space volume, multiple planet gears of the planetary gear set are guided freely by a centering plate between adjacent housing plates. The planet gears of the planetary gear set have in each case one passage opening, which are connected by a channel system to a central pump inlet. It is thus possible to realize close fits and flushing of gaps.

A system for forming a product from a food mass that includes: a hopper with a rotating feeder; a mould drum with cavities to form products; a feed pump having a moving member; and a divider located between the feed pump and the mould drum and configured to distribute the food mass over an axial length of the mold drum, the divider is directly connected to a housing of the feed pump or is integral with the housing of the feed pump, the divider has at its inlet side a slightly sloped sidewall, having an angle of between 10 degrees to 30 degrees relative to a longitudinal axis of the divider and a height of 20 mm to 40 mm, to distribute the food mass and a seal provided between the divider and the mould drum downstream of the divider and in contact with a surface of the mould drum.

A flow-through assembly for use in a downhole drilling string includes a Moineau-type motor, means for selectively activating the motor such as a ball catch component that selectively causes drilling fluid to enter into or bypass the motor, and a rotating variable choke assembly that is driven by a rotor of the motor. The choke assembly varies the flow rate of drilling fluid as rotation causes ports of the choke assembly to enter into and out of alignment with each other. In one embodiment, the choke assembly comprises a faceted rotary component including bypass ports on the facets of the component. In another embodiment, the choke assembly comprises a tapered rotary component that rotates in a complementarily tapered stationary component.

An integrated pump device includes a motor, an oil pump rotated by a driving force of the motor and configured to discharge oil drawn from an oil pan, and a hydraulic actuator configured to switch between an advance state and a retard state by a hydraulic pressure created by the oil pump. The hydraulic actuator is a parking lock actuator, and includes a housing having vane chambers and a vane rotor housed in the housing and including vanes arranged in the vane chambers. The vane rotor is configured to rotate to enter the advance state when the hydraulic pressure is supplied to an advance chamber, and to rotate to enter the retard state when the hydraulic pressure is supplied to a retard chamber. The parking lock actuator locks a parking lock mechanism at the advance state, and unlocks the parking lock mechanism at the retard state.

One example of a gerotor pump includes an inner rotor comprising multiple teeth, the inner rotor configured to rotate about a first longitudinal gerotor pump axis. The gerotor pump also includes a hollow outer rotor including an outer surface and an inner surface having substantially identical contours, the inner surface configured to engage with the multiple teeth and to rotate about a second longitudinal gerotor pump axis. The pump includes a pump housing within which the inner rotor and the outer rotor are disposed, wherein the outer surface of the outer rotor defines gaps between the pump housing and the outer rotor.

An electric oil pump comprises a stator assembly and an electronic control panel assembly which are electrically connected. The electronic control panel assembly comprises an electronic component. The electric oil pump further comprises a conductive pump housing and a conductive member that electrically connects a reference ground layer of the electronic control panel assembly and the pump housing. The above arrangement facilitates reducing electromagnetic radiation of the electronic control panel assembly, thereby reducing interference of the electromagnetic radiation of the electronic control panel assembly on the electronic component and/or other external devices.

A technique facilitates efficient well production in relatively low volume applications, e.g. applications after well pressure and volume taper off for a given well. According to an embodiment, use of an electric submersible progressive cavity pump is enabled in harsh, high temperature downhole environments. A pump stator facilitates long-term use in such harsh environments by providing a composite structure having an outer housing and a thermoset resin layer located within the outer housing and secured to the outer housing. The thermoset resin layer is constructed with an internal surface having an internal thread design. Additionally, an elastomeric layer is located within the thermoset resin layer and has a shape which follows the internal thread. In this manner, the elastomeric layer is able to provide an interior surface generally matching the shape of the internal thread of the thermoset resin layer and arranged for interaction with a corresponding pump rotor.

A flexible impeller pump designed for use in dispensing a flowable food product is disclosed. The flexible impeller pump includes a cover, impeller assembly and a pump body that are assembled to create the pump without other separate components. The components can be permanently connected to each other to create a disposable pump or can be disassembled for cleaning and reuse. The impeller assembly includes an impeller shaft and a flexible impeller molded over the impeller shaft to prevent separation. The impeller assembly is received within the pump body and the cover is secured to the pump body. The cover includes a seal that is molded over the pump body to prevent separation of the seal from the cover. The impeller shaft extends through the pump body and is coupled to a drive shaft of an electric motor that is operable to drive the impeller pump.

A method for controlling a permanent magnet (PM) synchronous motor in an ESP application is provided. A load angle of the PM motor is estimated. A voltage adjustment value is determined for the PM motor based at least on the estimated load angle of the PM motor. A voltage to be applied to the PM motor is determined based on the voltage adjustment value.
