A housing 11 has an axial passage 13 and an annular valve seat 40<SP>1</SP> at the base of a cavity forming part of the passage, a member 46 being fixed in the cavity and streamlined for providing substantially unimpeded flow past the member, the latter extending towards the valve seat and terminating in an annular surface 47 spaced from and parallel to the seat. A valve disc 40 is movable by a nipple 10 to an open position, wherein the disc is closely adjacent the surface 47 and within the contour of the member. As shown, the nipple 10 and housing are connected by balls 31 radially movable into a groove 19 in the nipple by a spring-loaded sleeve 32, which together with a collar 20 on the nipple, abuts a split retaining ring 35.</p> |
