Title: NON-RETURN VALVE FOR A FLUID PUMP
Abstract:
The invention relates to a non-return valve (1) for a fluid pump, in particular of a safety brake system of a motor vehicle, comprising a through-flow opening (7) which can be closed by a valve element (10), wherein the valve element (10) can be displaced against the spring force of a valve spring (11) made of coiled round wire in order to expose the through-flow opening. The round wire is coiled in one plane and is arranged with respect to the valve element (10) such that the plane extends at least substantially perpendicularly to the displacement direction of the valve element (10).
