Abstract

PURPOSE: To eliminate one of the pumps of steering control mechanism by providing an orifice sequence valve and a shuttle valve for detecting the output of a main pump to branch or join the steering passage and the operating passage.
CONSTITUTION: The output of a main pump 4 flows through an orifice 63 and chambers 11, 12 and 13 and reaches a steering passage 16 and joined with the flow from a steering pump 3, then flows into a tank through a steering passage 20, a central chamber 21, a passage 22, a float control valve chamber 67, an operating passage 14 and an operating valve 64. When the pressure loss at the orifice 63 became greater than then force of a spring 92 as the increase in the engine speed, a squence spool 95 is shifted to the right to connect a chamber 113 and 103 the oil before the orifice 63 is introduced into a chamber 105 through a passage 102, chambers 12 and 14a are connected as pistons 114 and 112 are shifted to the right so that the output of the main pump 4 is changed from the passage 16 to the operating passage 14.
