Abstract

PURPOSE: To prevent occurrence of negative pressure and air suction in anoil strainer suction partm by connecting an oil line from the oil discharge port of an oil pressure regulating valve to a feed oil line at the oil pump side of an oil strainer and decreasing a flow rate of oil to the oil strainer.
CONSTITUTION: In an oil hydraulic controller, there are providd a primry oil pressure regulating vlve 8, consisting of a spool 9, 10 and compression spring 11, and a secondary oil pressure regulating valve 31, consisting of a spool 32 and compression spring 33. Then an oil line 40 from an oil discharge port 37 of the seconary regulating valve 31 connected to the side of a suction port 1a from an oil strainer 3 in a suction oil line 4 to an oil pump 1. In this way, even in case of racing an engine at N-range, a flow rate of oil passing through the oil strainer can be maintained to a less level, causing no occurrence of ngative pressure or air suction in a suction part of the oil strainer.
