Abstract
PURPOSE: To dilute and adjust a working negative pressure securely with the air at a proper time by an arrangement wherein a rod to work according to a thermowax to sense an engine cooling water temperature is provided, and two valves are operated step by step in accordance with expansion and contraction of the rod.
CONSTITUTION: At the time of warming-up when an engine cooling water temperature is low, a negative pressure regulating device 10 is kept in the state as illustrated, a leak air passes an air passage 26 through a filter 19 connected to the atmosphere, comes to a negative pressure passage 8 through negative pressure leak passage 25 and nipple 27 and dilutes a working negative pressure of EGR valve 17 with the atmosphere. When the cooling water temperature exceeds a given value after warming-up, a wax pellet in a case 11 swells, and the rod 13 elongates against a spring 29, therefore a valve seat 14a of the first valve 14 and a valve seat unit 16 come in contact to close the passage 25. where the cooling water temperature further rises, only the rod 13 descends in a through hole 24 and comes to contact an adjust screw 23 to depress the second valve 15, thus opening the passage 25 again.
