Abstract
An oil separator for a compressor comprising a tank and a lid for the tank, which comprises, in an integral manner, a valve body defining an outlet duct of the separator, a head of a coalescence filter, a body of an anti-condensate valve, a body of a minimum pressure valve and the relative connection ducts.
Claims11
An oil separator (6) for separating oil from compressed air generated by a compressor, the separator comprising an oil tank (11) for compressor lubrication oil and a lid (12) for the tank, wherein the lid (12) integrally comprises a valve body (20) defining an outlet duct (27) of the tank (11), a head (28) of a coalescence filter (17) for separating oil from compressed air, a body of an anti-condensate valve (13), a body (31) of a minimum pressure valve (14) and the relative connection ducts, wherein the body (32) of the anti-condensate valve (13) defines a first chamber (60) housing a thermally sensitive element (34) of the anti-condensate valve and communicating with an air outlet duct (30) of the coalescence filter (17), and a second chamber (65) housing a shutter (66) operated by said thermally sensitive element and designed to interrupt the communication between an inlet duct (69) connecting the second chamber (65) to the minimum pressure valve (14) and a vent duct (68) when the temperature of the air in the first chamber reaches a predetermined threshold value.
An oil separator (6) for separating oil from compressed air generated by a compressor, the separator comprising an oil tank (11) for compressor lubrication oil and a lid (12) for the tank, wherein the lid (12) integrally comprises a valve body (20) defining an outlet duct (27) of the tank (11), a head (28) of a coalescence filter (17) for separating oil from compressed air, a body of an anti-condensate valve (13), a body (31) of a minimum pressure valve (14) and the relative connection ducts, wherein said minimum pressure valve (14) defines a first pressure threshold value, which ensures the correct lubrication of the compressor (4);
- said minimum pressure valve defining a concentrated load loss between an outlet duct (30) of the coalescence filter (17) and a delivery duct (37) for pressure values lower than the first threshold value, and
- wherein said minimum pressure valve (14) defines a second pressure threshold value sufficient for supplying of the utility, said second value being greater than the first pressure threshold value but smaller than the maximum pressure defined by a pressure switch of the compressor (4), said minimum pressure valve (14) being designed to connect the outlet duct (30) of said coalescence filter (17) to said anti-condensate valve (13) for pressure values exceeding said second threshold value.
