摘要

The infiltration check valve, particularly for water supply installations, has three differently operating exits and entries (A,B,C), a check valve and an infiltration valve, which having regard for their freedom of movement necessary for their operation are mechanically connected to each other. The check valve permits flow from A to B and blocks flow from B to A. The infiltration valve permits flow from B to C and blocks it from C to A and from C to B. Flow from B to C, whereby the part flow is parallel to the main axis of the infiltration-check valve, moves opposedly to the direction from A to B. The infiltration valve and/or the check valve is/are loaded with a spring force and/or a damping force.
