Schnellvervindungs- und Schnellöse-Kupplung.

摘要

A coupling comprises a hollow body (A) with a valve (D) supported therein to define an annular chamber for receiving a mating stem component. A slide sleeve (E) is mounted for axial movement in the annular chamber to control flow past the valve (D). Carried on the slide sleeve (E) is a wiper (I) mounted for sliding movement and having an end face which substantially fills the open end of the annular chamber. A pair of slide hooks (J) act to engage the stem component and move the slide member (E) to a closed position when the coupling is disconnected. The slide hooks (J) extend through slots in the wiper (I) and are held in engaged position in the slide sleeve (E) by co-operating surfaces on the hooks and the wiper. A pair of opposed dog-type detent members (K) is maintained in a radially outward position by the outer surface of the wiper (I) when the coupling is disconnected. In addition, the body (A) and a co-operating sleeve (110) for the detent members (K), are provided with a substantially elliptical cross-section which results in a stronger coupling design and facilitates guiding of the components.
