Self-closing tap valve

A self-closing dispensing valve for pressurized fluids comprising in combination:

• a valve housing enclosing a pressure space with an inlet port and an outlet port, the inlet port being part of a connection to a source of pressurized fluid and the outlet port being surrounded by a valve seat on the upstream side of the outlet port;
• a valve closing member arranged in the pressure space of the housing so as to face the valve seat, the valve closing member cooperating with the valve seat to normally close the outlet port under the effect of the pressurized fluid;
• and
• an elongated hollow outlet member supported by the valve housing, the outlet member having an axial outlet bore in communication with the outlet port, at least when the valve is open;
• and wherein
• the valve closing member has a generally plate-shaped outline, being liftable from the valve seat in a tilting motion of random tilt orientation;
• the outlet member has on its upstream extremity an enlarged spherical head portion which cooperates with the valve housing to form a ball-and-socket connection giving universal pivotability to the outlet member;
• the outlet member further has on its upstream end an annular face in the form of a truncation on its spherical head portion arranged to cooperate with a contact face on the downstream side of the valve closing member, so that a randomly oriented pivoting movement of the outlet member away from a normal position in which said two faces are aligned causes the annular face of the outlet member to move against the contact face of the valve closing member, thereby tilting and laterally lifting the latter from the valve seat to open the valve.
