Abstract

PURPOSE: To ensure the valve opening time for a highland as is permisible to the flat land by changing the area of an orifice communicating two diaphragm chambers according to the height.
CONSTITUTION: A lower chamber 101 of an after burn preventing valve 100 is directly communicated to a suction pipe 3 at the downstream of a throttle valve 4 through the first signal path 6 while an upper chamber 103 thereof is communicated to the suction pipe 3 at the downstream of the throttle valve 4 through a height sensing valve 200. The height sensing valve 200 is provided in a casing 201 having an air releasing hole 201a with a bellows 202 which could be set under the pressure equal to the atmospheric pressure at the altitude of 1,000 m for example. As the altitude exceeds 1,000 m, the bellows stretchs to lower a valve body 211 thereby reducing the path area of a large orifice 209. Accordingly, the area of the orifice changes according to the altitude to make up for the valve opening time of the after burn preventing valve 100.
