摘要： An electromagnetic solenoid for use with a fluid control valve is disclosed in which a fixed iron core and a casing for housing a solenoid coil can be fabricated separately from each other without difficulty, and in which the configuration and the clearance between the fixed iron core and a movable iron core or the length of the extension of the fixed iron core from an end wall of the casing can be readily changed in accordance with the desired magnetic attraction characteristics thereof as required. The cylindrical casing has an end wall formed at its one end and is open at its other end, the open end being closed by an end cap member to form a yoke for a magnetic circuit. The fixed iron core is adapted to be separably connected with the end wall of the casing. An output rod is disposed in the casing with its one end extending outwardly through the end wall of the casing, the output rod slidably extending through the fixed iron core and being supported at its opposite ends by the end wall of the casing and the end cap member through a pair of slide bearings for axial sliding movement. A movable iron core is received in the hollow of the solenoid coil and fixedly mounted on the output rod in a face-to-face relation with the fixed iron core. The end wall of the casing has an insertion bore formed therein, and the fixed iron core has its one end firmly fitted into the insertion bore.

摘要： An electromagnetic solenoid for a fluid control valve includes a cylindrical casing accommodating a solenoid coil and having an end wall formed at its one end and which is open at its other end, the open end of the casing being closed by an end cap. A fixed iron core is disposed in and fixedly mounted on the casing. An output rod is disposed in the casing with its one end extending outwardly through the casing end wall for connection with a valve member of the fluid control valve. The output rod slidably extends through the fixed iron core and is supported on its opposite ends by a slide bearing disposed in the end wall of the casing and by a slide ball bearing disposed in the end cap member. A movable iron core is received in the solenoid coil for axial sliding movement and is firmly mounted on the output rod in a face-to-face relation with the fixed iron core at a location such that the distance between the center of the movable iron core and the slide ball bearing is less than the distance between the center of the movable iron core and the slide bearing. The output rod and the slide bearing in the casing end wall are formed of a non-magnetic material.In one embodiment, the end wall of the casing has a fluid passage formed therethrough for providing fluid communication between the interior of the casing and the outside. In another embodiment, the slide bearing in the end wall of the casing has a fluid passage formed therethrough for providing fluid communication between the interior of the casing and the housing bore.

A pressure control valve is interposed in the control oil path for controlling the oil pressure so as to be equal to or lower than a predetermined highest pressure, and a bypass is provided for bypassing the upstream side and the downstream side of the main orifice. A device for increasing the oil pressure is provided in the bypass for closing the bypass to increase the oil pressure in the overall control oil path only when the oil pressure on the downstream side of the pressure control valve is equal to or lower than a predetermined lowest value.

摘要： A steering control apparatus for a vehicle includes a rockable auxiliary link for connecting an knuckle arm of a knuckle and the outer end of a tie rod of a steering unit to each other so that the relative position therebetween is variable. A rotor is rotatably mounted on the knuckle. A vehicle height detection link is connected between the rotor and a lower arm of a suspension of the vehicle so as to rotate the rotor in accordance with changes in the vertical stroke of the suspension. A control link is connected between the rotor and the auxiliary link so as to rock the auxiliary link in response to the rotation of the rotor, thereby changing the distance between the outer end of the tie rod and the steering axis of the knuckle.

摘要： The present invention incorporates a nipple to be inserted inside a hose and a sleeve formed concentrically with the nipple. An annular groove is formed on the outer periphery of the nipple to receive the expanded portion of the rubber toward the tip end of the nipple when the sleeve is caulked and to prevent the rubber from bulging at the tip end of the nipple. The annular groove is configured so that it can receive a portion of the inner rubber wall of hose when the hose is inserted between the nipple and the sleeve when the latter is caulked. The annular groove may be located on the outer periphery of the nipple, such as at a position offset from being in-line with where the sleeve is caulked and nearer to the tip end of the nipple. The number of annular grooves is not limited to one, and may be plural. When plural grooves are formed, they may be arranged adjacent to each other or spaced at a given interval.
