| A pump having a rotor that is rotatable about a rotation axis and comprises a rotor hub and a rotor collar that extends from the rotor hub in the radial direction and encircles it in an undulating manner, a pump housing which forms a pump duct with the rotor, said pump duct connecting a first inlet/outlet space to a second inlet/outlet space and a blocking device which is arranged between the first inlet/outlet space and the second inlet/outlet space and which comprises a blocking element which blocks the pump duct in the axial direction on both sides of the rotor collar. The blocking device has a first seat and a second seat for the blocking element, wherein the spacing between the first seat and the second seat in the circumferential direction is greater than the spacing between a first contacting face and a second contacting face of the blocking element in the circumferential direction. The invention also relates to a pump having a blocking device which includes a chamber formed in the pump housing, wherein the chamber and the blocking element are configured such that an exchange duct is formed in the axial direction between an axially front fluid chamber and an axially rear fluid chamber on the opposite side of the rotor collar, and to a corresponding blocking element. | ||||||
| 137 | POSITIVE DISPLACEMENT TRANSFER GEAR PUMP FOR MOLTEN METAL | US15431581 | 2017-02-13 | US20180230995A1 | 2018-08-16 | Bruno H. THUT |
| A self-cleaning transfer gear pump for transferring molten metal includes the following features: a transfer conduit extends upward from an outlet of a base, two rotatable gears are formed of refractory material and disposed in the gear chamber and engage each other during rotation. A boss functioning as a bearing extends from the drive gear and is adapted to be received in an opening in the base. A shaft is fastened at a lower end to the drive gear. A filter is fastened to the base so as to cover the inlet and prevents particles and objects in the molten metal from entering the gear chamber. In operational mode, a motor rotates the shaft and the drive gear whereby the drive gear and the second gear engage each other while being rotated so as to positively displace molten metal from the inlet to the outlet and along the transfer conduit to the remote location. In self-cleaning mode, the motor rotates the shaft and the drive gear effectively to draw molten metal from the transfer conduit by positive displacement, through the outlet, and toward the inlet therefore cleaning the filter by removing the particles adhering to the filter. Also included are a system with optional filter and optional self-cleaning mode but including an inlet portion of a die casting machine, and a method for operating the gear pump. A flow sensor may be used to transmit pulses into and from the transfer conduit so as to enable determination of a volume of molten metal being charged. The control of the molten metal volume being charged is not solely controlled by the flow sensor. | ||||||

| A positive-displacement pump, in particular a vane-type pump for the delivery of a fluid for a consumer of a steering system includes a rotor, a cam ring, a housing-side control plate, and a cover-side control plate that form, in an assembled state, a rotor assembly. The housing-side control plate is arranged adjacent to a housing face surface in an axial direction and the cover-side control plate is arranged adjacent to a cover face surface in the axial direction. The rotor assembly is movable in the axial direction between the housing face surface and the cover face surface. | ||||||
| 139 | OIL SUPPLY DEVICE AND METHOD OF CONTROLLING ELECTRIC OIL PUMP | US15576708 | 2016-05-12 | US20180135624A1 | 2018-05-17 | Kan YASHIMA; Takashi DOI |
| The objective of the present invention provides an oil supply device in which a negative pressure in a pump chamber is reduced or eliminated when an electric oil pump is shut down, thereby preventing air from entering the pump chamber and allowing oil to be supplied or recirculated smoothly. This oil supply device includes: an electric oil pump in which a rotary volumetric change pump provided with an inner rotor and an outer rotor is caused to operate by means of a motor; and an electric oil pump controller which controls the motor in such a way that, when the electric oil pump is to be shut down, the rotary volumetric change pump is caused to temporarily stop, after which the rotary volumetric change pump is caused to rotate by a predetermined angle in the opposite direction to the direction of rotation during oil supply, and is then shut down. | ||||||
| 140 | LAUNDRY-CARE APPLIANCE COMPRISING A METERING SYSTEM | US15567188 | 2016-03-23 | US20180135228A1 | 2018-05-17 | Bernd HABERLANDER; Hans EGLMEIER |
| The present invention relates to a laundry-care appliance (100) comprising a metering system (105) for metering a first liquid substance and a second liquid substance, wherein the metering system (105) comprises a first storage container (107) for providing the first liquid substance, a second storage container (109) for providing the second liquid substance, and a pump unit (112) which comprises a first pump head (113) and a second pump head (115). The metering system (105) comprises a common drive (129) for driving the first pump head (113) and the second pump head (115), wherein the common drive (129) can be driven in a first drive direction (137) and in a second drive direction (139). The first pump head (113) is designed in the case of the first drive direction (137) of the common drive (129) to convey the first liquid substance in a first conveying direction (149) from the first storage container (107). The second pump head (115) is designed in the case of the second drive direction (139) of the common drive (129) to convey the second liquid substance in a second conveyor direction (153) from the second storage container (109). | ||||||
