Abstract
An automatic condensate removal device Fig. 1 (not shown) for location at the bottom of an air receiver or air filter in a compressed air system has a restricted fluid inlet 16 connected to the system and a condensate removal outlet 28 controlled by a main valve 22 biased to its closed position by a spring 26 and movable to an open position by air pressure in a chamber 38 acting on a diaphragm 34 when the pressure in the system communicated to a chamber 32 on the other side of the diaphragm decreases. When the air pressure in the system is increasing, the pressure in the chamber 38 also increases, since air passes thereto from the inlet 16 via a chamber 14, a filter 31, the chamber 32, a slot 73 in a valve stem 60 associated with the valve 22, a passage 40 and through an opening 46 controlled by a valve 48 urged to the closed position by a spring 50. Upon a decrease in the pressure in the system the pressure in chambers 14, 32 also decreases whereupon pressurized air trapped in the chamber 38 moves the diaphragm 34 and the valve stem 60 which opens the main valve 22 and allows condensate and air to pass to the outlet 28. The opening of the valve 22 further lowers the pressure in chambers 14, 32 resulting in continued opening of the valve 22 until the valve 48 movable with the diaphragm 34 is opened by abutment with a pin 74 on which the stem 60 is slidable, thereby releasing pressure from the chamber 38 whereby the main valve 22 closes. In a further embodiment, Fig. 4 (not shown) the valves are of different construction but they perform the same function as those described.
