摘要： An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.

摘要： A pump device having a vane-type pump has a check valve in a fluid duct which leads from a pressure region to an under-vane region. The check valve blocks in the direction of the pressure region, preventing pressure from escaping from the under-vane region into the pressure region during the start-up of the vane-type pump.

摘要： A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.

摘要： A turbomachine that can be operated as a motor and as a pump, having an axially fixedly mounted shaft, including a power section with rotating inlet and outlet and an associated controller. Because the axial forces (Fgx) have been made independent of the sense of rotation the turbomachine is significantly more reliable, and because the sealing forces have been adjusted it has significantly greater reliability (η) in both running directions. It can be operated with fluids and gases. The turbomachine can be extended by adding a control device and a drive for the control device so as to provide a freewheel function, a braking function and/or blocking function, and so as to shift, modify and optimize the characteristic curves across the entire control range. In both the clockwise and anticlockwise directions the turbomachine has in principle the same properties, although these can be modified and optimized by the control device.

摘要： A gear pump includes: a first pump constructed from a first drive gear rotated by driving of a drive shaft and a first driven gear rotatably arranged coaxially with a rotary shaft; and a second pump constructed from a second drive gear rotatably provided coaxially with the rotary shaft and a second driven gear. The rotary shaft allows the first driven gear and the second drive gear to engage with and disengage from each other in a rotation direction by movement to an axial direction. When the discharge pressure is higher than predetermined pressure, rotation of the first driven gear is not transmitted to the second drive gear and only the first pump operates. When the discharge pressure becomes the predetermined pressure or less, the rotation of the first driven gear is transmitted to the second drive gear and the first and the second pumps operate.

摘要： A water pump assembly for an internal combustion engine including a housing, as well as first and second rotatable shafts supported by the housing. First and second pulleys are fixed for rotation with the first and second shafts, respectively. A pumping member is fixed for rotation with the second shaft. A flexible member engages the first and second pulleys and is sized to slip relative to one of the first and second pulleys when in an unloaded state. A control mechanism selectively applies a load to the flexible member to cease the slipping and drivingly interconnect the first and second pulleys to rotate the pumping member.
