Abstract
The invention relates to a check valve, for use as an insert check valve, with a valve seat and a valve element that is resiliently prestressed against the valve seat by a valve spring. According to the invention, a retaining element embodied as a retaining bracket is provided, which supports the end of the valve spring remote from the valve element and the retaining element can be locked resiliently to a recess, particularly an annular groove, of the valve housing. This enables fast, simple assembly of the check valve from its individual parts.
