A valvefixed on a tipof a rodas a moving part, abuts a sealing partof a fluid passagewhen the rodmoved to the left, and interrupts a flow of fluid, is made, for instance, of elastic materials such as rubber. This absorbs an impact generated when the valve is sealed (at the time of collision), and reduces loudness of an actuating sound caused by a collision between the valveand the sealing part
