314 PUMP DEVICE US16334778 2017-09-25 US20190234406A1 2019-08-01 Kazuhiro HOMMA; Yosuke ITO
A pump device includes a shaft, a motor to rotate the shaft, and a pump driven by the motor via the shaft to discharge oil. The pump device includes a first flow path for oil to connect an interior of the pump and an interior of a housing, a second flow path for oil provided between a stator and a rotor included in the motor, a third flow path for oil disposed outside in a radial direction or inside in the radial direction of the stator and the rotor, and a fourth flow path to cause oil from the second flow path or the third flow path to flow into the pump.
315 PUMP DEVICE US16334775 2017-09-25 US20190234405A1 2019-08-01 Kazuhiro HOMMA; Yosuke ITO
A pump device includes a shaft, a motor that rotates the shaft, and a pump driven by the motor through the shaft to discharge oil. The pump device includes a first passage that sucks oil from an intake opening of the motor, a second passage which is provided between a stator and a rotor, and a third passage connected from the second passage to a negative pressure region inside the pump, and the pump discharges oil flowing from the third passage to the pump from the discharge opening.
316 VANE PUMP US15763833 2016-09-02 US20180306182A1 2018-10-25 Yoshiyuki MAKI; Tomoyuki FUJITA; Tomoyuki NAKAGAWA; Masamichi SUGIHARA
A vane pump includes a rotor; a plurality of slits that are formed in the rotor, the plurality of vanes being respectively inserted into the plurality of slits in a slidable manner; a cam ring that has a cam face on which tip-ends of the vanes slide by the rotation of the rotor; and pump chambers that are defined by the rotor, the cam ring, and an adjacent pair of the vanes. The plurality of vanes have a plurality of first vanes that are formed by applying a DLC coating on a base material and second vanes that are formed such that the base material is exposed, the first vanes being respectively inserted into at least two adjacent slits of the plurality of slits.

The cartridge vane pump includes a first connection channel that connects a first discharge port and a first discharge channel and a second connection channel that connects a second discharge port and a second discharge channel. An O-ring is provided on an outer circumference of a circular tube portion, the O-ring blocks communication between the first connection channel and the second connection channel.
318 Pump including a spring fastened to positioning elements US15130105 2016-04-15 US10087929B2 2018-10-02 Claus Welte
A pump including a rotor; a first housing part and a second housing part, between which the rotor is arranged such that it can be rotated about a rotational axis relative to the first and second housing part; at least one positioning element which positions the second housing part with respect to its angular position about the rotational axis relative to the first housing part; and a spring, wherein the second housing part is arranged between the spring and the rotor, wherein the spring is fastened to the at least one positioning element or the second housing part.
319 CARTRIDGE VANE PUMP US15760464 2016-09-08 US20180258928A1 2018-09-13 Tomoyuki NAKAGAWA; Masamichi SUGIHARA; Yoshiyuki MAKI
A cartridge vane pump includes a head pin that penetrates through a cover, a cover-side side plate and a cam ring that are fixed to an adapter. The head pin has a shaft portion that is fixed to the adapter at a tip end thereof, and a restricting portion that has a diameter larger than that of the shaft portion and being formed on a base end of the shaft portion. The cam ring, the cover, the cover-side side plate and a body-side side plate are held between the restricting portion and the adapter.

A vane pump includes a high-pressure chamber formed as a groove in a bottom portion of a pump-accommodating concave portion. The working fluid is discharged from a plurality of discharge ports leading to the high-pressure chamber. A high-pressure passage has an opening portion opening to the high-pressure chamber and guides the working fluid to the outside of the high-pressure chamber. In the vane pump, one of the plurality of discharge ports is arranged so as to face the opening portion of the high-pressure passage, and the flow-passage cross-sectional area of the high-pressure chamber is smaller than the total flow-passage cross-sectional area of the plurality of the discharge ports.
