Title:
PRESSURE REGULATING VALVE
Document Type and Number:
Japanese Patent JP2017155814
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure regulating valve capable of restricting enlargement of a fixing part in a radial direction when the fixing part is fixed between a first piping and a second piping.SOLUTION: A pressure regulating valve 1 comprises a valve chamber 55, a valve body 60 and a coil spring 61. The valve chamber 55 comprises a first opening 56 communicated with a first piping 11, a second opening 57 communicated with a second piping 12, a fuel flowing-out port 58, an annular valve seat 59 and a flow passage 80 in the valve chamber for connecting the first opening 56 with the fuel flowing-out port 58 through a valve seat 59. The valve body 60 is positioned at a downstream side in a fluid flowing direction S from the valve seat 59. A coil spring 61 causes the valve body 60 to be abutted against the valve seat 59 and energizes it to a shutting-off position 60A where the flow passage 80 in the valve chamber is shut off. The valve body 60 has a first pressure receiving surface 76 for receiving fluid pressure through the first opening 56, a second pressure receiving surface 77 for receiving fluid pressure through the second opening 57 and a valve flow passage 73 of which one end is opened to the first pressure receiving surface 76 and the other end is opened to the second pressure receiving surface 77.SELECTED DRAWING: Figure 3
