摘要： An idling engine speed control valve has an electromagnetic coil (6), a plunger (1) adapted to be attracted to the electromagnetic coil, a spring (7) urging the plunger so as to apply thereto a force balancing with the attractive force of the electromagnetic coil, a pilot valve seat (9) provided on an end surface of the plunger, a hollow shaft (10) formed separately from the plunger with a main valve (13) and a diaphragm (11) mounted fixedly thereon, and a pilot valve (15) formed at one end of the hollow shaft so as to be opposed to the pilot valve seat. The hollow shaft is supported so that it can be slid in the axial direction thereof, and the end of the hollow shaft carrying the pilot valve (15) is in contact with the diaphragm and positioned in a chamber (20) communicating with the atmosphere via an orifice (14), the end of the hollow shaft which is on the opposite side of the pilot valve-carrying end thereof communicating with the portion of a throttle unit which is on the downstream side of a throttle valve (101). The control valve has a means, for example spring (16a;16b), for applying to the main valve a force large enough to fill any diminution of valve opening force in an engine starting operation under low-temperature conditions.

摘要： A fluid control valve which regulates a flow rate of a liquid and, more particularly, which controls a fluid by axially moving a valve body fixed to a valve shaft (105). The fluid control valve comprises a device (13) for absorbing vibrations of the valve shaft (105) in a direction perpendicular to the axis thereof. More specifically, there is provided a device (13) for exerting a pressing force to lightly press the valve shaft (105) against the inner walls of bearings (106, 129). Alternatively, the valve shaft (105) may be held between a plurality of elastic plates fixed on the inner surface of a valve casing (101). A support member for such a valve shaft (105) used in the fluid control valve comprises a disk (16) having a center hole through which the valve shaft (105) is inserted, an annular member (15) formed around the disk (16), and an elastic piece (14) one end of which is secured to the disk (16) or the annular member (15), while the other end of the elastic piece (14) is extended to the vicinity of the center of the hole, so that the annular member (15) is fixed on the inner surface of the valve casing (101), and that the distal end of the elastic piece (14) is pressed against the valve shaft (105) which is extended through the hole. According to the invention, vibrations of the center shaft (105) in radial directions can be suppressed to prevent unstable movements of the valve (104).

摘要： Automotive engine idle speed control device meters the flow rate of air supplied to the engine bypassing an intake pipe thereof during engine idle operation to thereby control the engine idle speed. An actuating vacuum is produced in accordance with an electrical signal and acts on a diaphragm (33) fixed to a valve member (25) movable with the diaphragm (33) to meter the bypass air flow. To cancel any external force acting on the valve, compensation means (39 - 43) is provided to control the vacuum on the diaphragm (33) independently of the electrical signal to displace the diaphragm in a direction (44) opposite to the direction (45) of action of the external force on the valve (21, 22, 23).
