Abstract

The quick coupling has a union for the connection of a pipe, for the supply of a fluid, and an opening which can be shut off for the introduction of a union for delivery of the fluid to a user. Situated inside the quick coupling is a fixed stem, forming a valve head and interacting with a valve seat formed by tubular means which can be moved against the action of spring means. The end of the stem which faces the inlet of the fluid under pressure has a circumferential groove which receives with geometrical mating a support disc consisting of two half-bodies which can be assembled and which have a central seat which surrounds the stem in the region of the circumferential groove. Each half-body has at least one opening for the passage of the fluid supplied. The assembled support disc is inserted and locked locally in a seat made in the body of the quick coupling.
