Abstract

PURPOSE:To instantaneously transmit positive pressure of a signal chamber to an output port in a valve control device applied to ignition timing control or the like, by concurrently providing a check valve, allowing a flow from a side of the signal chamber only to the direction of an output chamber side, with an orifice. CONSTITUTION:If a turbocharger is operated, an area in the vicinity of a throttle valve is changed to positive pressure, and an ignition angle advancing device causes a delay angle of ignition timing in accordance with the positive pressure through a control valve devic 20. Now the positive pressure is fed from a port 21, then a check valve 61 is opened to instantaneously transmit the positive pressure to an output port 23, further a difference is not caused in pressure between chambers 44, 45 to hold a valve 65 to a closing state by the positive pressure in a chamber 48. Then the turbocharger is not operated to feed negative pressure to the port 21, when the negative pressure is approximate to the atmospheric pressure, the valve 65 and the check valve 61 are closed and the pressure is transmitted to the port 23 through an orifice 57. When the negative pressure is approximated to a vacuum with pressure in a port 32 to the atmosphere, the valve 65 is opened to decrease a level of the negative pressure, by the atmosphere and the pressure is output from the port 23.
