Abstract
A lubricant fitting (10) adapted to be detachably connected to a valve body (11). The lubricant fitting (10) includes an elongate body (12) that has a central bore (24) therethrough which has an intermediate bore portion (26) that joins opposite inner and outer bore end portions (28 and 30) of an enlarged diameter. Inner and outer annular seats (32 and 34) are formed at the junctures of the intermediate bore portion (26) and the inner and outer bore end portions (28 and 30), respectively. An elongate valve member (50) is mounted within the central bore (24) and has inner and outer valve elements (52 and 54) which have inner and outer shoulders (64 and 86), respectively. The inner and outer annular shoulders (64 and 86) are in opposed facing relationships to the inner and outer annular seats (32 and 34), respectively. A threaded connection (92) exists between the inner and outer valve elements (52 and 54), and allows the inner and outer valve elements (52 and 54) to move longitudinally relative to each other upon the relative rotational movement between themselves to selectively place the inner and outer bore end portions (28 and 30) in fluid isolation so that the lubricant fitting (10) provides an adequate seal between the interior of the valve body (11) and atmosphere at all normal operating pressures within the valve body (11).
