Patent ID: 8512482

Claim:
A device for blocking passage of fluid in a household appliance, the device comprising: a tubular element including a receiving portion configured for flow of fluid therethrough; a substantially hollow tubular insertion body configured for receipt in the receiving portion of the tubular element; a check valve having a sealing element and a contact region configured as a valve seat and formed in the tubular element, the sealing element being disposable against the valve seat in a sealing position for blocking passage of fluid in a first direction from the tubular insertion body to the receiving portion of the tubular element and being displaceable from its sealing position against the valve seat to an open position for allowing passage of fluid in a second direction that is opposite the first direction the tubular insertion body supporting the sealing element at an end thereof disposed adjacent the contact region of the check valve, at least a portion of the tubular insertion body comprising a soft-elastic material and being elastically deformable such that the tubular insertion body is, in an installed position in the receiving portion of the tubular element, elastically deformed and fixed in an axial position relative to the tubular element with the sealing element bearing against the contact region in a sealing manner, wherein the sealing element is attached at a pivoting end to the insertion body in a pivotable manner such that the sealing element pivots between the sealing position and the open position, and the sealing element has a free end opposite the pivoting end, the free end moving away from the contact region as the sealing element moves from the sealing position to the open position.
