Claims

[Scope of utility model registration request]

When the intake manifold negative pressure introduced into the diaphragm chamber via the negative pressure pipe exceeds a certain value, an idle-up diaphragm device that drives the throttle valve to open to the idle-up opening, and an idle-up diaphragm device in the middle of the negative pressure pipe are provided. an air control valve that is arranged and opened according to the load of the power steering pump during power steering operation to open the negative pressure pipe; and for the negative pressure pipe;
a second negative pressure pipe connected in parallel with the air control valve; and an atmosphere introduction port disposed in the middle of the second negative pressure pipe, the air introduction port and the second negative pressure pipe selectively opening and closing the intake manifold side port of the passage, and 1. a solenoid valve that introduces atmospheric air into a port on the side of the idle-up diaphragm device of the atmospheric pipe line, and whose atmospheric air introduction port is closed when the cooler is switched on; and a position between the solenoid valve and the idle-up diaphragm device. and a negative pressure delay consisting of an orifice and a check valve that is arranged in the second negative pressure conduit and is parallel to the orifice and allows air to flow only from the idle up diaphragm device side toward the solenoid valve. An idle up device for an internal combustion engine, comprising a valve.
