Abstract
PURPOSE: To open and close a valve directly under the control of suction negative pressure by designing a sub-throttle valve to be opened continuously.
CONSTITUTION: A continuously opened sub-throttle valve 40 is equipped in the downstream of a main throttle valve 34, which only closes in low-load operation. When a suction negative pressure is zero or smaller than a specified value, a diaphgram 44 is displaced downwards by a spring 52 and the sub- throttle valve 40 connected to the diaphgram is kept open. So, the spring 52 used for a diaphgram can be also applied as a spring of a continuously opened sub- throttle valve 40. when a suction negative pressure increases over a specified value in low negative pressure operation involving idiling, the diaphgram 44 moves upwards and the connected sub-throttle valve 40 is closed.
