Abstract

An oil exchange apparatus (16, 96, 126) and its assembly with an arrangement (17) of fluid flow lines (112), (108), for lubricating a system, such as an engine (15, 145), while providing for a quick exchange of the apparatus (16, 96, 126) with another one when another batch of oil is to lubricate the system. A filter (30, 103, 135) is mounted and disposed in a receptacle (21, 97, 128); inlet conduits (144, 109, 132) and outlet conduits (34, 105, 136) are mounted to the receptacle (21, 97, 128) and by which oil flows in and out of it in the operation of the system. A vacuum or vent conduit 43 also is mounted to the receptacle in each of its embodiments. In one embodiment, all the conduits (34, 44, 43) are mounted in a top housing component (22) of the receptacle (21). In other embodiments, inlet (109, 132) and outlet (105, 136) conduits are mounted at the receptacle's bottom (101, 130), while the vacuum/vent or third conduit (115, 141, 156) is at its top (102, 142). A pump (127) is disposed in the receptacle (128) in the one embodiment. In the assembly of apparata (16, 96, 126) and lines (112, 108 and 117, 141, 156), quick-disconnects (107), (111), (155) and (138), (137), (143) provide the connection between corresponding apparatus and lines, while the lines at their other ends are connectable to the housing (145) of the system's engine. A pump (157) is mounted in the return line (108) in one embodiment, and a pump (161) is mounted across both the return line (112) and the flow line (108) to the apparatus in another embodiment.
