| 摘要 |
The present invention provides a simplified and easily manufacturable collet type tube coupling. The preferred embodiment provides a first fluid fitting body having a substantially straight inside bore which may be stepped or unstepped, and an engagement member (26), such as a radial opening (27), that may be engaged by a rib on a separate collet to form the assembly of the collet type tube coupling. A tube may be restrained in the first fluid fitting body by action of the collet. A key to the present invention and its manufacturing simplicity is that an engagement member (26) may be made that does not require a larger inner bore cavity dimension than the entrance bore, such as a reverse inside taper so prevalent in the marketplace. The first fluid fitting body may include a radius slide (48) to assist the engagement and disengagement of the rib with the engagement member (26). In the preferred embodiment, the first fluid fitting body and collet may be unitary pices. The invention may also include an integral skirt and a swivel member. |
