Title: Air treatment unit
IPC: F15B21/048
Filed: 1974-04-10
Abstract: 1470798 Air-cleaning apparatus; mixing flowing fluids WILKERSON CORP 10 April 1974 [13 April 1973] 15992/74 Headings B1C and B1T [Also in Division F2] A unit for cleaning and possibly injecting lubricating oil into and pressure regulating compressed air comprises an upper manifold 12, secured demountably between -wallmounted brackets 68 which connect to a compressed air pipeline, and a lower housing 14 which encloses a pair of bowls 36L, 36R and holds them in demountable sealing relationship with the manifold. As shown upstream bowl 36L encloses baffles 106 and filter 108 which remove water and solids from the air, and downstream bowl 36R encloses a body of oil which is progressively forced up tube 124 and through drip tube 128 to be atomised and entrained by the air passing through orifice 118 to lubricate machinery downstream. The downstream bowl could alternatively enclose a second filter. Both bowls have drain plugs 60, and the unit is symmetrical so that the manifold and housing can be reversed relative to brackets 68 and to each other. Fig. 3 shows a pressure regulator located in series between the two bowls, but this could be omitted (Figs. 5, 6 not shown), in which case passages (152) and 156 are not drilled out. As shown the pressure regulator comprises a valve 160 urged by spring 174 on to annular seat 154. A valve stem 158 extends from valve 160 and normally closes an aperture in a piston 92 which is urged upwards by spring 46 and downwards by the air pressure in space 20 connected by aperture (172) with the region 114 downstream of the valve. The downstream pressure is thus controlled at a constant level depending on the axial position of stem 158 in valve 160, which is adjustable by knob 162 and lock knob 164. Housing 14 supports a pressure guage (24) connected by passage 42 to the main air channel. Manifold 12 has symmetrically arranged channels (138, Fig. 4 not shown), one of which connects to passage 42 in each possible orientation of the housing while the other is closed off. Housing 14 has windows 34 for observation of the plastics bowls 36. Housing 14 is connected to manifold 12 (Figs. 1, 2, not shown) by having front and rear flanges (180) which embrace end tongues (178) of the manifold. Pins (184) are then inserted through aligned holes in flanges and tongues and retained in inserted position by spring rings (190).
