PURPOSE: To enhance the lubricity of a governor, in a device in which blowby gas is introduced from a crankcase into a governor chamber where the governor housed, by providing the governor chamber with a blowby gas discharging part, so that the introducing quantity of blowby gas to the governor chamber can be increased.
CONSTITUTION: The governor weight 26 of a centrifugal governor gives a forward governor force 32 to a governor lever 29 by the expandedly opening motion due to a centrifugal force caused by its rotation via an engaging part 27, a flange 23, and a governor shaft 22, so that the position of a fuel quantity regulating pin 31 is changed by means of a governor lever 28 in the balance with the spring force 33 exerted on the spring lever 29. And the blowby gas including lubricating oil mist is introduced into a governor chamber 2 where the governor 1 has been housed from a crankcase 3 via a fuel injection pump chamber 14 for lubricating the governor 1. In this case, a discharge pipe 38 as a blowby gas discharging part 4 is inserted into the cover body 37 of the inspection hole 36 of the governor chamber 2, so that the introducing quantity of blowby gas to the governor chamber 2 can be increased.
