Abstract: A hydraulic control apparatus is provided including: an electromagnetic valve that has an input port communicating with a supply destination unit of oil and a control port that is switched between communication and disconnection by resultant force of a hydraulic pressure of the supply destination unit and electromagnetic force; a variable displacement pump which has a suction port communicating with a supply source of the oil, an ejection port communicating with the supply destination unit, and a control chamber communicating with the control port and rotates in accordance with drive of the supply destination unit, in which an amount of the oil ejected to the supply destination unit through the ejection port changes in accordance with a pressure in the control chamber; and a control unit that controls a value of a necessary current that is caused to flow through the electromagnetic valve.

Abstract: To provide a rotor portion 2A; a cam ring 21 having a rotor chamber 21a; a pump housing 1 provided with a pump chamber 11 having a control chamber 12 where the cam ring 21 is movably arranged to move the cam ring 21 using an oil pressure; a spool valve A for controlling the cam ring 21; a solenoid valve 81; and a relief valve 83. Each valve housing is provided with a communication hole 7 for supplying oil from the control chamber 12 of the pump chamber 11 to a portion between the control chamber 12 and at least one of the valve housings. A through-hole for discharging the oil is formed in the valve housing.

Abstract: A waterproof plug (10) for a waterproof connector includes a body (11) of a generally cylindrical shape. A wire (28) can be inserted into the body to be projected therefrom, and an outer peripheral surface (12) of the body can be press-contacted with an inner peripheral surface (23) of a cavity (22), while an inner peripheral surface (13) of the body can be press-contacted with the wire (28), and an insulation barrel (26) of a terminal (25) can compressively clamp the wire (28) through the body. An insertion hole (16) in the body is tapering such that a thickness t of a clamping portion (18) of the body is uniform along an axis thereof.
