  • Patent number: 5507534
    Abstract: A fitting (10) for dispensing fluids, such as hot melt adhesives, includes a swivel member (12) and a housing (14). The swivel member (12) has a ball (16) at one end which is received within a socket (22) of the housing (14). The swivel member (12) has a first bore (24) which intersects and cooperates with at least one secondary bore (28). The secondary bore (28) is generally perpendicular to the first bore (24) and to a conduit (54) in the housing (14). Fluid enters the first bore (24), passes into the secondary bore (28), passes into a reservoir (40) and then finally into the conduit (54) and out of the housing (14). The reservoir and the orientation of secondary bores 28 reduces or eliminates axial loading on swivel member (12) due to the internal fluid pressure.
