PURPOSE:To prevent the adhesion and buildup of deposit in an auxiliary air regulation valve having a pin-formed valve body and thus prevent seizure in the valve body or its inferior operation. CONSTITUTION:A temperature sensing auxiliary air regulation valve 4 is disposed integrally with a housing 2 having an auxiliary air control valve 3. The auxiliary air regulation valve 4 has a pin-formed valve body 32 moving forward and backward within a valve opening 31 a, and it controls the path area according to the temperature of thermowax within a wax case 34. A bypass path 39 is formed, bypassing the valve opening 31 a in starting from a control valve chamber 15 of the auxiliary air control valve 3, in which is disposed an idle adjust screw 40. A tip of the bypass path 39 opens toward side face of the valve body 32, so that high-velocity air flow is injected into the valve body 32. |
