摘要： A known power steering system of the type in which movement of a steering wheel is transmitted via a torsion bar to an oil path switching valve to actuate a power cylinder in a desired steering direction by switching a high pressure oil pump to the oil path switching valve and a low pressure oil path extending from the oil path switching valve to an oil tank and a part of working oil flowing through the high pressure oil path is led to a reaction piston to restrain torsion of the torsion bar, is improved by providing a main orifice disposed in the high pressure oil path and a control oil path branched from the upstream side of the main orifice in the high pressure oil path and communicating with the reaction piston. 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： 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.

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.
