Abstract

A pressure chamber of a valve-opening air spring (48) is supplied with compressed air within a reservoir tank (62) via a non-return valve (65). On the other hand, a pressure chamber of a valve-closing air spring (46) is selectively supplied, by a switching valve (82) via the non-return valve (65), with compressed air within the reservoir tank (62) and compressed air within a high-pressure reservoir tank (80) whose pressure is higher than that within the reservoir tank (62). In order to forcibly increase the pressure within the pressure chamber of the valve-closing air spring (46) immediately before seating of a valve element (21), the compressed air supplied to the pressure chamber of the valve-closing air spring (46) is switched to the compressed air within the high-pressure reservoir tank (80). By this type of a control apparatus of an electromagnetic valve, an increase in power consumption of the electromagnetic valve is suppressed.
