摘要： A proportional electromagnetic valve includes a valve main body having a valve member, a solenoid to drive the valve member, and an amplifier unit to control the solenoid. The solenoid is attached to one or both side portions of the valve main body. The amplifier unit has a size which is almost equal to a size on the unit attaching surface side of the valve main body and solenoids. The casing of the amplifier unit has an enclosing space large enough such that single printed board having all of drive amplifiers attached there to placed in the casing of the amplifier unit.

摘要： When a solenoid has been turned on by supplying current to a coil thereof, the solenoid operation is checked by temporarily ceasing the supply of current to the coil to temporarily deenergize the solenoid. The current flowing in the coil is detected while the solenoid is temporarily deenergized, and the characteristics of the thus detected current are used to discriminate the position of a movable iron core of the solenoid. On the other hand, when the solenoid has been turned off by ceasing the supply of current to the coil, the solenoid operation is checked by temporarily supplying current to the coil to thereby temporarily energize the solenoid. The current flowing in the coil while the solenoid is temporarily energized is detected, and the characteristics of the thus detected coil current are used to determine the position of the movable iron core of the solenoid.

摘要： A differential pressure regulator is arranged in series on the inflow side of a variable throttle for adjustment of a flow rate. An inlet pressure of the variable throttle is led into a primary pilot chamber of the differential pressure regulator. A constant flow control valve is provided in an oil passage connecting an oil passage on the inflow side of the differential pressure regulator with a secondary pilot chamber in order to allow a fluid of a constant flow rate to flow. The inflow side of a sequence valve is connected to the side of the secondary pilot chamber of the differential pressure regulator. The outflow side of the sequence valve is connected to the outlet side of the variable throttle or a tank. The inlet passage of the variable throttle is led into the primary pilot chamber of the sequence valve. An outlet pressure of the variable throttle is led into the secondary pilot chamber of the sequence valve. Further a check valve or a throttle is connected in parallel to the sequence valve. A relief valve is provided in an oil passage starting from the outflow side of the constant flow control valve and reaching the tank in order to prevent an increase in peak pressure when a load stops and thereby to control the pressure.
摘要翻译：差压调节器串联布置在可变节流阀的流入侧，用于调节流速。可变节气门的入口压力被引导到差压调节器的主导向室中。恒流量控制阀设置在油通道中，该油通道将差压调节器的流入侧上的油通道与次级先导室连接，以允许恒定流量的流体流动。顺序阀的流入侧连接到差压调节器的次级先导室侧。顺序阀的流出侧连接到可变节流阀或罐的出口侧。可变节气门的入口通道被引导到顺序阀的主先导室。可变节流阀的出口压力被引导到顺序阀的次级先导室。此外，止回阀或节气门与顺序阀并联连接。溢流阀从恒流量控制阀的流出侧开始设置在油路中并到达油箱，以防止当负载停止时的峰值压力增加，从而控制压力。
