A brake control device for vehicles includes a master cylinder, a plurality of wheel cylinders, and an anti-lock control apparatus disposed between the master cylinder and the wheel cylinders of at least one hydraulic circuit. The anti-lock control apparatus includes a hydraulic pump, a reservoir and a changeover device which is selectively changed over at least between a first condition which permits an increase in the hydraulic pressure of the wheel cylinders of at least one hydraulic circuit and a second condition which permits an decrease in the hydraulic pressure of the wheel cylinders of at least one hydraulic circuit in response to the locking condition of the road wheels. The hydraulic pump includes a housing, a slidable piston device for defining a pump chamber which is communicated with the reservoir and the changeover device at a side of one end thereof in the housing, an inlet check valve disposed between the pump chamber and the reservoir for permitting fluid communication from the reservoir to the pump chamber and for interrupting fluid communication from the pump chamber to the reservoir, an outlet check valve disposed between the pump chamber and the changeover device for permitting fluid communication from the pump chamber to the changeover device and for interrupting fluid communication from the changeover device to the pump chamber, and a piezo element for reciprocating the piston device disposed at the other end of the piston device.

A sealing member fitting apparatus includes a sealing member transfer device that switches between a sealing member receiving position where the sealing member transfer device faces a sealing member holding device provided with a hollow sealing member and a sealing member fitting position where the sealing member transfer device faces an electrical wire clamping device. The sealing member transfer device receives the sealing member in the sealing member receiving position and fits the sealing member on a covering end portion of the electrical wire in the sealing member fitting position. An electrical wire insertion guide device is disposed between the sealing member transfer device and the electrical wire clamping device and is slidable along the electrical wire from a lead-out member to the covering end portion. The sealing member transfer device positions a central axis of the covering end portion substantially coaxially with a central axis of the sealing member.

A terminal insertion apparatus having a wire holding unit holding two wires, each wire having a terminal, a connector holding unit holding a connector housing having at least two holes for receiving terminals, and a terminal insertion head is disclosed. The terminal insertion head has a wire gripping unit having a first holder and a second holder. The first holder and second holder are movable in a vertical direction toward and away from the wire holding unit and are movable in a horizontal direction toward and away from the connector holding unit. The first holder has an outer grip and an inner grip that together hold one of the two wires while the second holder has an outer grip and an inner grip that together hold the remaining of the two wires.

摘要:
A diaphragm-type vacuum pump device which includes a diaphragm, a pumping chamber the volume of which is changed by reciprocating motion of the diaphragm, a check valve for drawing air into the pumping chamber, a check valve for discharging air from the pumping chamber and an orifice or relief valve disposed in the pumping chamber so that the pumping chamber communicates with atmosphere.

An electrical apparatus is disclosed which comprises a combination of a solenoid device such as a solenoid valve, a relay or a plunger driving solenoid device and an energization control circuit which energizes the solenoid device. One end of an electrical cable is connected to the solenoid valve while the other end of the cable is connected to a connector. The electrical cable prevents the transmission of oscillations which the solenoid valve experiences to the connector. The energization control circuit is housed within the connector. The energization control circuit responds to a changing of a given switch from its on to its off condition, by energizing the electrical coil only during a given time interval. When the time interval has passed, it interrupts the energization of the electrical coil, and the energization control circuit itself is substantially disconnected from the power source.
