1. A dispensing valve, particularly for large containers, comprising a tubular valve member (14, 44, 76), one tubular end of which constitutes an outlet opening (19, 47, 87) and which adjacent to its other end has at least one lateral inlet opening (16, 79) and which is mounted in a guide bore (13, 43, 75) of a housing (1, 1a, 1b ; 2, 2a, 2b ; 3a,3b, 24, 25, 75) to be slidably movable against the force of a closing spring (18, 46 ; 81) like a piston by a handle from a closing position to a dispensing position, in which its inlet opening (16, 79) emerges from the guide bore and communicates with the interior of the container, wherein a valve plate (15, 77) is provided on that part of the valve member (14, 44, 76) which is inwardly directed from the inlet opening (16, 79) and in the closing position engages a valve seat, and the valve is adapted to be fixed in its open position, characterized in that the guide bore (13, 43, 75) for the tubular valve member (14, 44, 76) is provided on a screw-in nipple (10, 35, 71) which is provided with an outer head part (10, 10a, 10b, 36, 72) that constitutes a support for an assembling seal (11, 11a, 11b) the valve member (14, 44, 76) is rotatably mounted in the guide bore (13, 43, 75) and the region for engagement of locking means (21, 22, 48, 84, 85, 86) which serve to fix the valve member in at least one rotational positon when it is in its open position which is provided in a region between the outside surface of the housing, which outside surface faces the handle, and the hangle itself, the locking means consist either of magnet retainers (21, 22), including a magnet (22) and an associated armature (21), which are mounted on the housing (3, 34) and an actuating member (20) that is secured to the valve member (14) and said magnet and armature are eccentric with respect to the axis of the valve member (14) so that they can interengage only in a specific rotational positon of the valve member, or, if the handle (45,82, 83) consists of a cap which is open toward the nipple and receives the valve spring (46, 81) and is guided on the nipple (35, 45), said cap and the nipple carry indentations and detent elements (48, 84, 85, 86) which constitute the locking means. |
