Abstract

Improvements introduced in a check valve, with a valve box with valve seat, at least one closing part that cooperates with the last part that is supported with possibility of tilting in the valve box, and with at least one closing spring maintained stationary in the valve housing and having a pivotably movable active arm that attacks the closure piece, characterized in that the closing spring is disposed in the inner chamber of the valve housing located on the inflow side and because in the active arm and/or in the closing part, a drive member is provided which engages the active arm with the locking element in the swiveling direction of the closing part and connects them with each other with the possibility of relative slip in the longitudinal direction of the active arm.
