The invention discloses a car idle speed control valve which comprises a valve base, a lower cover connected with the valve base, a sleeve assembly arranged on the upper portion of the valve base and a coil bag assembly arranged in the sleeve assembly. The valve base is provided with a first cavity, a second cavity and a third cavity from top to bottom in sequence. A through way communicated with the third cavity is arranged on the inner cavity wall of the first cavity. A first through hole is formed between the first cavity and the second cavity. A second through hole is formed between the second cavity and the third cavity. A first pressing spring and a sealing rod which is arranged on the first pressing spring and extends upwards are arranged in the valve base. A first sealing structure and a second sealing structure which are matched with the first through hole and the second through hole respectively are arranged on the sealing rod. A valve rod component is arranged at the upper end of the sealing rod. The problem that the opening degree of an existing idle speed control valve can be easily affected by external pressure difference fluctuation is solved, and product idling is accurate.
Description
technical field [0001] The invention relates to an automobile control valve, in particular to an automobile idle speed control valve. Background technique [0002] The idle speed valve of the automobile is installed on the bypass air hole of the throttle body, and the speed is adjusted by controlling the air volume of the bypass throttle body. The idle speed controller is based on the ignition signal, and when the engine speed is lower than 750rpm (rev / min), The idle speed valve acts to increase the engine speed, and when the engine speed exceeds 1050rpm (revolutions per minute), the idle speed valve stops acting. At present, the most widely used in the world is the stepper motor type idle speed valve, which includes a rotor composed of permanent magnets, a stator composed of excitation coils, and a feed screw and valve that convert rotary motion into linear motion. The signal is converted and controlled, so that the rotor can rotate forward or reverse, so that the screw ro...
