A thermal valve unit is provided for use with an oil filled screw compressor. The thermal valve unit can be affixed to an exterior pipe segment and can include a thermally responsive element in thermal communication with compressed air traversing through the pipe segment. The valve unit can include a movable valve member actuated by the thermally responsive element that opens and closes oil passages to selectively route oil either to a heat exchanger prior to being delivered to the oil filled compressor, or directly to the compressor without passing through the heat exchanger.

1. An apparatus comprising: a compressor thermal valve unit having: a thermal valve housing having an exterior shell that includes a plurality of apertures through which a first fluid can traverse, the housing enclosing an interior having a plurality of passages in fluid communication with the plurality of apertures and through which the first fluid from the apertures can pass;a base disposed near an end of the thermal valve housing and structured to support the thermal valve when affixed to a compressed air system pipe, the base having a thickness that extends from a bottom surface and a footprint defined in part by a lateral length, the bottom surface of the base having a shape complementary to an external side surface of the pipe, wherein the thickness is shorter than the lateral length, and wherein the lateral length extends along an axial direction of the pipe; anda thermal valve having a valve body coupled to a thermally responsive element, the thermally responsive element in thermal contact via intermediate structure or directly exposed to compressed air which traverses the compressed air system pipe during operation, the thermally responsive element configured to directly assess temperature of the compressed air, the valve body structured to move in response to excitation of the thermally responsive element from a temperature of the compressed air so as to open and close one or more of the plurality of passages within the thermal valve housing for the passage of the first fluid. 2. The apparatus of claim 1, which further includes a neck disposed between the thermal valve housing and the base, wherein the neck includes a cross sectional area smaller than a cross sectional area of the thermal valve housing and smaller than a cross sectional area of the thermal valve base. 3. The apparatus of claim 2, wherein the exterior shell includes a plurality of opposing faces within which are formed the plurality of apertures. 4. The apparatus of claim 1, which further includes a pipe to which the thermal valve unit is affixed, the pipe having an inlet and an outlet and a side opening aperture that permits fluid flowing from the inlet to outlet to contact a portion of the thermal valve unit. 5. The apparatus of claim 4, which further includes a sealant disposed between the base and the external side surface. 6. The apparatus of claim 5, wherein the external side surface includes an embossment upon which the base is coupled, wherein the sealant is an O-ring, and wherein the O-ring disposed between the embossment and the base. 7. The apparatus of claim 5, which further includes the compressed air system pipe, a compressor structured to provide the compressed air to traverse the compressed air system pipe, an oil filter, and an oil heat exchanger, and wherein the first fluid is oil. 8. The apparatus of claim 7, wherein the thermal valve unit is a unitary stand-alone component manufactured separately from the pipe. 9. An apparatus comprising: a compressor valve unit for use with a compressor and having a housing within which is contained a plurality of reconfigurable fluid flow paths structured to selectively flow a first fluid;a temperature responsive element disposed within the compressor valve unit and coupled to a movable valve member, the temperature responsive element configured to directly sense a temperature of a second fluid by virtue of being in thermal contact via intermediate structure or directly exposed to the second fluid and thereby actuate the movable valve member from a first position to a second position based upon the temperature of the second fluid, the first position connecting a main inlet to a main outlet, the second position connecting the main inlet to a heat exchanger outbound port and a heat exchanger inbound port to the main outlet; anda mounting base disposed at an end of the compressor valve unit for an external contact with a compressor pipe, the mounting base having a lateral periphery in the circumferential and axial directions with dimensions sized to close off an accessory opening formed in an outer surface of the compressor pipe, the accessory opening oriented transverse to a bulk fluid flow path of the compressor pipe. 10. The apparatus of claim 9, wherein the mounting base includes a recess configured to receive a sealing member, wherein the pipe to which the mounting base is configured to mount is annular in nature, and wherein the mounting base forms a non-annular shape. 11. The apparatus of claim 9, wherein the mounting base is planar and includes a groove into which can be fitted a sealing member. 12. The apparatus of claim 11, wherein the reconfigurable fluid flow paths are in fluid communication with the main inlet, the main outlet, the heat exchanger outbound port, and the heat exchanger inbound port, and wherein the housing includes a plurality of faces within which are located the main inlet, the main outlet, the heat exchanger outbound port, and the heat exchanger inbound port. 13. The apparatus of claim 12, wherein the housing is quadrilateral in cross sectional shape such that the main inlet, main outlet, heat exchanger outbound port, and heat exchanger inbound port are dispersed around the housing, and wherein the compressor valve unit further includes a neck between the housing and the mounting base. 14. The apparatus of claim 12, which further includes a pipe having an internal passage structured to convey fluid between opposing openings on either end of the pipe, the pipe further including the accessory opening. 15. The apparatus of claim 14, wherein the outer surface of the compressor pipe further includes an embossment to which is attached the compressor valve unit. 16. The apparatus of claim 15, wherein the embossment includes a planar mounting surface, wherein the mounting base includes a planar base surface, and wherein the planar base surface is configured to mount direct to the planar mounting surface of the embossment. 17. The apparatus of claim 16, which further includes the compressor, an oil filter, and an oil heat exchanger.
