Abstract

PURPOSE: To prevent white smoke emission at engine braking and also to decrease oil consumption by a method wherein a throttle valve opening is interlocked to control an oil discharge and a controlling mechanism to decrease the oil discharge at the time of increase in suction negative pressure is provided.
CONSTITUTION: Where a lever 40 is turned according to an operation of a throttle valve, a reciprocating stroke of plunger in a pump 10 changes to vary a discharge. In this case, a negative pressure actuator 50 is interlocked with a control shaft 37 through lever 39 and rod 57, and suction negative pressure is introduced to the negative pressure actuator 50 through a negative pressure controlling device 60. When the suction negative pressure gets high to exceed a set point at the time of engine braking, a diaphragm 62 partitioning a negative pressure chamber 63 of the device 60 moves upward, and thus a valve disc climbs. The negative pressure controlled thereby is introduced into a negative pressure chamber 54 of the actuator 50, and the lever 39 turns to correct the shaft in the direction of throttle closing.
