UN COMPRESOR HELICOIDAL CON UNA VALVULA DE PASO QUE RESPONDE TERMICAMENTE PARA LA PROTECCION CONTRA LAS ALTAS TEMPERATURAS

Una válvula que responde térmicamente establece una descarga hacia el campo de succión en respuesta al accionamiento de un accionador térmico. El accionador térmico responde a la temperatura del piso del compresor fijo en una región cerca de la salida de modo que el accionador responde a las condiciones locales que indican una falla próxima. A shell has a suction chamber, and contains two coacting scroll members. The first scroll member has a wrap and a floor. A discharge path extends through the first scroll member. A bleed path extends through the first scroll member and connects the discharge path and the suction chamber. A normally closed valve in the bleed path includes a thermally responsive element. The thermally responsive element is located in the first scroll member at a position in proximity to the floor. An excessive heating of the floor in proximity to the thermally responsive element causes the thermally responsive element to open the normally closed valve and permit flow through the bleed path.
