摘要： A valve element (12) of a pressure reducing valve includes a taper portion (23) seated on an inner periphery of a valve hole (31). The valve hole (31) includes a first area (33), a second area (34) and a third area (35) in order from an upstream side. The first area (33) is provided such that, when the valve element (12) is open, the height of a passage defined between the first area (33) and the taper portion (23) gradually reduces toward a downstream side. The second area (34) is provided such that the height of a passage defined between the second area (34) and the taper portion (23) is constant when the valve element (12) is open and the entire second area (34) contacts the taper portion (23) when the valve element (12) is closed. The third area (35) is provided such that, when the valve element (12) is open, the height of a passage defined between the third area (35) and the taper portion (23) gradually increases toward the downstream side.

摘要： In a pressure reduction valve device, a valve body (22) and a distal end portion (60a) of a support member (60) are accommodated in a valve accommodation hole (10a) of a body (70). The distal end portion (60a) is inserted through an urging member accommodation hole (22d). An inner introduction passage (80) is formed between an outer peripheral surface of the distal end portion (60a) and an inner peripheral surface of the urging member accommodation hole (22d). An outer introduction passage is formed between an outer surface of the valve body (22) and an inner surface of the valve accommodation hole (10a). The support member (60) is provided with communication holes (60e) that establish communication between a gas inlet provided through the body (70) and the valve accommodation hole (10a) in an axial direction. The inner introduction passage (80) and the outer introduction passage (81) are opposed, in an axial direction thereof, to the communication passage (60e).
摘要翻译：在减压阀装置中，阀体（22）和支撑部件（60）的远端部（60a）容纳在主体（70）的阀容纳孔（10a）中。前端部（60a）插通于施力部件收容孔（22d）。在前端部（60a）的外周面与施力部件收容孔（22d）的内周面之间形成有内导入通路（80）。在阀体（22）的外表面和阀容纳孔（10a）的内表面之间形成外引入通道。在支承部件60上设有连通孔60e，该连通孔60e使在主体部70上设置的气体入口与阀收容孔10a在轴向上连通。内导入通路80和外导入通路81在轴向上与连通路60e相对。

摘要： The pressure reduction valve includes: a cylindrical portion, a piston and a spring. The cylindrical portion includes an inlet communicating with the primary side flow path and an outlet communicating with the secondary side flow path. The piston fitted into the cylindrical portion is slidable along an axis direction of the cylindrical portion within the cylindrical portion, and defines, within the cylindrical portion, a space communicating with the inlet and the outlet. The spring applies, to the piston, a force acting toward the space. The outlet is displaced in one direction from the center of the piston when seen in the axis direction. The force applied to the piston by the spring is distributed so as to deviate from the center of the piston to the side of the outlet.
