<p>PROBLEM TO BE SOLVED: To improve workability of an engine cylinder block by changing an oil pressure feeding position of an oil pump 6 and provide a plunger guide 47 improving pump pressure resistance and maintaining magnetizing efficiency. SOLUTION: An oil feeding port 20 connected to an oil feeding passage 7 on the oil pump 6 side is arranged on a tip surface of a sleeve 13 of an electromagnetic oil pressure control valve 1. A drain port 23 connected to an oil discharging passage 9 on the drain side is arranged on a side surface of the sleeve 13 of the electromagnetic oil pressure control valve 1 to provide an oil feeding passage 7 formed in the engine cylinder block in a same axis as an attachment hole of the electromagnetic oil pressure control valve 1. A bottom wall part 57 of the plunger guide 47 is formed in a curved surface shape bulging toward the side opposite to the oil feeding port 20 to improve pump pressure resistance without increasing wall thickness of the plunger guide 47.</p> |
