Quick-fitting coupling for simultaneously connecting or disconnecting a plurality of couplings

Abstract

The quick-fitting coupling (1) has arranged thereon spring-loaded flat-face sealing couplings with interengaging male and female members (2,3) to serve as hydraulic couplings. The female member (2) of each flat-face sealing coupling is provided with an outwardly projecting peripheral flange (14) for precise embedded engagement with a respective peripheral groove on a mounting opening for the female member arranged on the fixed support plate (4), the arrangement being such that the flat end face (17) of the female member (2) comes to lie in a common plane with the coupling side (18) of the support plate (4) and is in abutting relationship therewith. Furthermore, the male members (3) are rigidly fastened to the movable support plate (5) and are projecting therefrom to a point so as to cause the two support plates (4,5), when the flat-face sealing couplings are in the coupled position, to be in abutting engagement with each other. This arrangement will render the quick-fitting coupling very compact and enable it to be coupled and uncoupled, even when under pressure, without leakage of hydraulic fluid. Due to the absolutely rigid mounting of the female members (2) as well as the male members (3) on the respective support plates (4,5), the interengaging coupling members of the flat-face sealing coupling are not subjected to any transverse forces during the coupling and uncoupling procedures and at the time when the coupling is in the coupled position. This feature is of particular advantage when using such quick-fitting couplings in the agricultural field and under relatively rugged conditions.
