Embodiment Construction
[0027] The valve closing body 10 comprises a hollow cylindrical guide element 12 and a spherical sealing element 14 . The guidance of the valve closing body 10 is significantly expanded in the axial direction by the guide element 12 and partially surrounds the sealing element 14 by means of the detent 16 . The sealing element 14 can be snapped into and fixed in the guide element by simple assembly steps. The valve closing body 10 is prestressed against a sealing seat 20 , for example a pump cylinder (not shown), by means of a return spring 18 sunk into the open end of the guide element.
