Title:
VALVE OPERATION SELECT DEVICE FOR INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS6053606
Kind Code:
A
Abstract:
PURPOSE:To make selecting operation ever so sure, by controlling the hydraulic passages at low pressure side of plural hydraulic actuators selecting operation characteristics of a valve independently each. CONSTITUTION:A hydraulic chamber 21a in which high oil pressure is led in a steady state and a hydraulic chamber 2a of a hydraulic actuator 2 for #1 cylinder use are interconnected to a hydraulic actuator 21 for #4 cylinder use. And, in order to interconnect other side hydraulic chambers 2b and 21b of these actuators 2 and 21 to each of independent passages leading the oil pressure at the low pressure side, a direction selecting valve performing selection control of the oil pressure is formed. With this constitution, these two actuators can be controlled for selection at optimum timing, and a direction selecting valve structure to be formed in one side actuator 21 and a piping structure to be connected to this valve structure can be simplified as well as control accuracy and reliability are thus improved.
