INTAKE APPARATUS HAVING INTEGRATED SOLENOID VALVE

摘要

An intake apparatus having an integrated solenoid valve according to the present invention includes: a valve body having a solenoid connected to a power source; a distribution block which has a vacuum flow path connected to a vacuum pressure while being combined to an upper part of the valve body, and has a first and a second flow path supplying a vacuum pressure or an atmospheric pressure by being connected to a first and a second actuator; a bushing which has a first and a second port linked to the first and the second flow path selectively while being combined to an inner space of the distribution block; a plunger which has a large diameter part and a small diameter part combined into the bushing while being able to slide, and has a first air flow groove linked to the first and the second port of the bushing selectively and a second air flow groove linked to the vacuum flow path of the distribution block and the first air flow groove in the large diameter part; and an elastic member giving elastic force to the plunger. Therefore, the present invention can improve output performance of an engine by increasing torque by improving intake efficiency by operating a variable intake valve and an overpass valve selectively through the first and the second actuator by the medium of the integrated solenoid valve in correspondence to a rotation speed of the engine, and can secure degree of freedom in design by reducing a required space of an engine room, and can reduce manufacturing costs in accordance with reduction of components accordingly.
