An electric oil pump includes a motor including a motor shaft, a pump assembly including a vane pump driven by the motor to suction and discharge oil, and an inverter to drive the motor. The motor includes a rotor, a stator on a side outward from the rotor in a radial direction, and a motor housing containing the rotor and the stator. The motor housing includes a suction port through which the vane pump suctions oil from outside, and a discharge port through which the vane pump discharges oil to outside. The motor housing includes flat surface portions in a portion of an outer periphery thereof. The suction port and the discharge port are located in a first surface of side surfaces which are the flat surface portions of the motor housing and are parallel or substantially parallel to the axial direction.

Electric oil pump

An electric pump provided with a pump unit configured to discharge working oil by being rotationally driven by an electric motor includes: a drive shaft configured to transmit rotational driving force from the electric motor to a rotor of the pump unit; a rotation-detection shaft provided coaxially with the drive shaft, the rotation-detection shaft being configured to be rotated together with the rotor; and a rotation detector unit configured to detect rotation of the rotation-detection shaft. The rotation-detection shaft has: an engagement portion configured to engage with the rotor; and a detection-target portion facing the rotation detector unit, and an outer diameter of the detection-target portion is set so as to be larger than an outer diameter of the engagement portion.

Electric pump

The pump device includes a motor portion that includes a shaft rotating about a central axis and a pump portion that is driven by a motor portion via the shaft. The pump portion includes a pump rotor that rotates along with the shaft and a pump housing that includes an accommodation portion that accommodates the pump rotor. The pump housing includes a pump body that includes a first bearing portion that supports the shaft and a pump cover with an accommodation portion disposed between the pump cover and the pump body. The pump cover includes a flow path through which oil is discharged and suctioned, and includes a second bearing portion that rotatably supports the shaft and that communicates with the flow path. An end portion of the shaft on one side in the axial direction is disposed at the second bearing portion or inside the flow path.

A print monitoring apparatus for monitoring a print transported out of a printing unit comprises a defect position discrimination unit for discriminating a position of a defect on a print web of the print fed from the printing unit, a defect memory unit for storing defect position information given from the defect position discrimination unit and record information containing defect occurrence time, a number of successive occurrence pages, a roll paper name and a number of used pages, and a display unit for displaying the information stored in the defect memory unit. In another aspect, a print monitoring apparatus for monitoring a print transported out of a printing unit comprises a print defect detection unit for detecting defect on a print web of the print fed from the printing unit, the defect detection unit including a monitoring sensor for dividing a print surface of the print web into a plurality of pixels and converting information of pixels into electric signals representing density information of the respective pixels, a central processing unit for processing information data regarding the density information of the respective pixels from the print defect detection unit, and a defect content discrimination unit for discriminating defect content in accordance with information data from the central processing unit and preliminarily set reference for the discrimination.

A multiple control valve system comprises the first and second multiple control valves. To the first multiple control valve an additional attachment valve is operatively connected in a manner that pressurized oil is supplied to the first multiple control valve and the attachment valve from a common oil pump independently through respective conduits. The second multiple control valve is connected to the attachment valve through a conduit to which a remote control valve is disposed thereby to change over flow direction changeover valves contained in the attachment valve and the second multiple control valve to simultaneously operate these valves.

Multiple control valve system

A multiple control valve system comprises a multiple control valve as a main body, an additional attachment valve operatively connected to the multiple control valve, a logic valve oil-tightly fitted to the multiple control valve so as to be communicated with oil passages formed in the multiple control valve, and a change-over valve operatively connected to a spool located in the attachment valve so as to be communicated with oil passages of the attachment valve and connected to the logic valve through a conduit.

A multiple control valve for operating a civil construction machine or the like comprises a valve body, at least two parallel direction change-over plungers assembled in the valve body, by-pass passages and fluid supply passages formed in the valve body and operatively communicated with the plungers for feeding fluid from an external source to the plungers. One of plungers disposed most downstream side of the multiple control valve is provided with inner passages arranged on both sides thereof, a passage crossing the plunger, an axial passage having one end closed and the other end opened towards one of the inner passages, and a lateral port communicated with the inner passage. The crossing passage is communicated with the axial passage at a portion near the closed end thereof. When the most downstream side plunger is displaced from its neutral position in a direction to operate a corresponding actuator for operating a mechanism of the machine in a predetermined direction, the crossing passage intercommunicates with one of the supply passage and the lateral port intercommunicates with the by-pass passage and when the most downstream side plunger and another plunger disposed upstream side thereof are simultaneously displaced in the direction described above, only the connection between the crossing passage and one of the supply passages is established.
