The control is for a combustion engine and responds to the pressure in the suction duct. It comprises a housing (40) with inlet duct (61), an outlet duct (62), and outlet (67) connected with the inside of the housing, and a valve (74). In its manual position, the valve connects the inlet (61) with the outlet duct (62) and with external control means. In its operating position, the valve closes the inlet and connects the outlet duct (62) to the outlet (67) and to the control means. A diaphragm (56) has a control chamber (50) on one side whilst the other side is connected with the valve. The chamber is connected (100) to the suction duct, so that the valve is held in its manual position by the vacuum, and moves to its operating position when vacuum fails. |
