ABSTRACT:
A suction system to an inlet valve of a reciprocating piston internal combustion engine consists of a suction line adapted to be closed by a closure valve and of a by-pass line by-passing the closure valve. A check valve is inserted into the by-pass line which is formed by slots in the suction line and spring lamellae covering the same from the outside. In order to reduce throttle losses and to permit a dynamic charging effect to become effective, the closure valve is fully opened at rotational speeds above 3,500 rpm.
