Full Text	This invention relates to a device for the removal of condensate water from the air systems. In the prior art, auto drain valve© are known for removing the condense water from the air systems. These valves are adapted to be fitted below the air tank and to a chamber provided for collection of condensate . The valve is actuated by an external signal preferably air signal. A signal air lift the valve which leads to draining out of the condensate from the water collection chamber. Means are provided with some devices to cut off the air connection between the air tank and the condensate collection chamber during the blow off operation to minimise wastage of compressed air. These systems have the following disadvantages:- 1. Discharge occurs irrespective of whether there is condensate or not, this results in considerable air wastage in dry seasons. 2. The discharge duration is fixed and in very wet seasons, condensate levels build up inside the tanks due to inadequate length of discharge. 3. The systems has to be fitted out side the tank which makes it vulnerable to damages in moving systems. The other devices /valves are also known in the prior art for the removal of the water from the air systems. Such type of devices /valves work on the principal of floats. These devices act only when there is water inside the tank. These devices consist of a condensate collection chamber connected to the tank on one side and the other side is opened to the atmosphere through the said float actuated valve/device. The condensate keeps collecting in the chamber and the float remains raising till the level of the water reaches a predeterminate level at which the float causes the removal of the water to the atemosphere. When the water is blown off the float returns to a lower level and thus closes the valve again. The main disadvantage associated with such devices is that these devices are bulky and fitted outside the air tanks. Also the floats are mechanically moving systems and are suceptible the damages and snags. Dribblers are also as such known in the prior art for the removal of the water from the air systems. These dribblers work on the basis on the internal signals generated by the pressure fluctuations inside the air tanks. The disadvantage associated with these devices is that the dribblers are fitted outside the tank and have limited use due to inadequate discharge which takes place irrespective of presence of condensate. Therefore the main object of this invention is to provide a novel device which is self-actuated and floatless device and adapted to work on the basis of the signals generated internally when there is water in the tank. Another object of this invention is to provide a novel device for use for the removal of water from the air systems and which is adapted to be fitted inside the tank- Yet another object of this invention is to provide a device which is light in weight and handy and easily install by the operator. Yet another object of this invention is to provide a novel device which is cheap in cost and the maintenance thereof is negligible. Further the device work efficiently. According to this invention, there is provided a device for the removal of condensate water from the air systems comprising a hollow body having a plurality of chambers provided therein, for accommodating a inner tube having an outer tube provided around the lower portion of said inner tube being disposed into said housing, a spring loaded piston being provided into the middle chamber of said housing to define second and third chamber therein a condensate filling passage being provided at one side of said housing for connecting the bottom end of the first chamber to the air tank, a pressure passage being provided at one side of said housing for connecting the second chamber with the air tank and equalising passage being provided at the other side of the housing for connecting the top end of the first chamber to the bottom end of the said second chamber, a flange being provided at the bottom end of said housing for accommodating the lower end of the outer tube therein and for securing said device with the air tank of the air systems.

A plurality of chambers for example a first/top chamber A is provided towards the top end of the housing H. Another chamber is provided in the housing H towards the bottom end of the first chamber A. In spring loaded piston 10 is disposed within the other chamber to divide the same into a second chamber 8 and a third chamber C. A seals 6 is provided towards the top end of outer tube to make it leak proof/airtide with the bottom end of the chamber A. A seal 15 is provided at the top end of the chamber 8 to make the outer tube as leak proof/airtide with the top end of the chamber B. A seal/o ring 17 is provided at the priphery of the spring loaded piston 10 disposed between the chamber B and C. Another seal/O ring 18 is provided at the inner side of the space provided between a third chamber C and fourth chamber D. A plurality of blow off pores 8 are provided towards the top end of the outer tube for facilitating the exit of condensate water stored in the bottom of the chamber A.

Normally, when there is no condensate or the condensate level is below the level of the condensate passage 16, chamber A and B are at tank pressure and also chamber C is at tank pressure, a valve 20 remains closed due to the pressure of the spring 9 and unbalanced air pressure on the valve poppet. The condensate keeps collecting in this position. When water level reaches the capillary 16 orifice, the orifice becomes choked for the passage of air. The pressure inside the chamber A and B drops due to leakage from the micro choke but the pressure in the chamber C reamins same as the tank pressure. The pressure differential so generated overcomes the spring and unbalanced force of the poppet and the valve opens and discharges the condensate into the atmosphere. When water is bown off, the air pressure of the tank blows the capillary clear and restores the air pressure inside the chamber A and B to the same level as the tank. This causes the valve to return to the closed position due to spring 9 force and unbalanced air pressure on the poppet. In both opening and closing operations, the condensate collected inside chamber A gets cleared through the step orifice 11 in the poppet. The above operations are repeated whenever the condensate level builds up inside the tank. The level may be chosen on the basis of the tolerable limit for condensate collection. WE CLAIM; I.
