Abstract An oil recovery apparatus to recover lubricating oil from an aerosol mist in an air driven machine where air is driven through an oil storage tank forming an aerosol which is carried to the contacting machine parts to be lubricated and out through a discharge passage comprising a vertical hollow case with an upper gas passage section and a lower storage section, there being an air inlet and outlet in said upper gas passage section, a vane separator in said upper gas passage section with vertical outer blades providing rotary motion to the aerosol-containing gas passing through said upper gas passage separating the heavier aerosol from the lighter gas, a baffle board extending between the upper and lower sections to receive aerosols thereon to enhance the liquid-gas seperation, upper and lower tanks in said lower storage section including a float in said upper tank and a duct between said tanks, valve means for feeding recovered oil from the upper tank to the lower tank across said duct including a valve portion between said upper and lower tanks a first passage extending from said lower tank to said valve portion having switching valve means therein controling said duct, a diaphragm chamber with a diaphragm in said first passage and a first valve rod for reciprocation in said first passage said valve rod being connected with said diaphragm and said switching valve means, a second vertical passage housing, a second valve rod connected to said float and air supply ports in said second vertical passage one of said ports communicating with said diaphragm chamber, a recess in said second valve rod allowing communication between said air supply ports to said diaphragm chamber acting on said first valve rod which in turn acts on said switching valve means to allow flow of oil down said duct, said switching valve means closing said duct flow as the float sinks to a predetermined level.

AN OIL RECOVERY APPARATUS TO RECOVER LUBRICATING OIL FROM AN AEROSOL MIST IN AN AIR DRIVEN WHERE AIR IS DRIVEN THROUGH AN OIL STORAGE TANK (B) FORMING AN AEROSOL WHICH IS CARRIED TO THE CONTACTING MACHINE PARTS TO BE LUBRICATED AND OUT THROUGH A DISSCHARGE PASSAGE (14) COMPRISING IN COMBINANATION: A. A VERTICAL HOLLOW CASE WITH AN UPPER GAS PASSAGE SECTION AND A LOWER STORAGE SECTION, THERE BEING AN AIR INLET (16) AND OUTLET (17) IN SAID UPPER GAS PASSAGE SECTION. B. A VANE SEPARATOR (21) IN SAID UPPER GAS PASSAGE SECTION WITH VERTICAL OUTER BLADES (23) PROVIDING ROTARY MOTION TO THE AEROSOL-CONTAINING GAS PASSING THROUGH SAID UPPER GAS PASSAGE SEPARATING THE HEAVIER AEROSOL FROM THE LIGHTER GAS, A BAFFLE BOARD (20) EXTENDING BETWEEN THE UPPER AND LOWER SECTIONS TO RECEIVE AEROSOLS THEREON TO ENHANCE THE LIQUID GAS SEPARATION, C. UPPER AND LOWER TANKS IN SAID LOWER STORAGE SECTION INCLUDING A FLOAT (39) IN SAID UPPER TANK AND A DUCT (26) BETWEEN SAID TANKS, D. VALVE MEANS FOR FEEDING RECOVERED OIL FRON THE UPPER TANK TO THE LOWER TANK ACROSS SAID DUCT (26) INCLUDING A VALVE PORTION (24) BETWEEN SAID UPPER AND LOWER TANKS A FIRST PASSAGE (28) EXTENDING FROM SAID LOWER TANK TO SAID VALVE PORTION HAVING SWITCHING VALVE MEANS (27, 29) THEREIN CONTROLLING SAID DUCT (26) A DIAPHRAGM CHAMBER (31) WITH A DIAPHRAGM (33) IN SAID FIRST PASSAGE AND A FIRST VALVE ROD 932) FOR RECIPROCATION IN SAID FIRST PASSAGE SAID VALVE ROD BEING CONNECTED WITH SAID DIAPHRAGM (33) AND SAID SWITCHING VALVE MEANS (27, 29), A SECOND VERTICAL PASSAGE HOUSING, A SECOND VALVE ROD (38) CONNECTED TO SAID FLOAT (39) AND AIR SUPPLY PORTS (40,41) IN SAID SECOND VERTICAL PASSAGE ONE OF SAID PORTS (41) COMMUNICATING WITH SAID DIAPHRAGM CHAMBER (31) A RECESS (43) IN SAID SECOND VALVE ROD (38) ALLOWING COMMINICATION BETWEEN SAID AIR SUPPLY PORTS AT CERTAIN POSITIONS OF THE FLOAT, AND SPRING MEANS HOLDING THE SWITCHING VALVE MEANS IN CERTAIN POSITIONS SO THAT THE RAISING OF THE FLOAT ABOVE A CERTAIN LEVEL RAISES SAID SECOND ROD PROVIDING COMMUNICATION BETWEEN SAID AIR SUPPLY PORTS (40,41) TO SAID DIAPHRAGM CHAMBER (31), ACTING ON SAID FIRST VALVE ROD (32) WHICH IN TURN ACTS ON SAID SWITCHING VALVE MEANS (27,29) TO ALLOW FLOW OF OIL DOWN SAID DUCT (26), SAID SWITCHING VALVE MEANS CLOSING SAID DUCT FLOW AS THE FLOAT SINKS TO A PREDETERMINED LEVEL.
