<p><P>PROBLEM TO BE SOLVED: To provide a valve unit having high durability even if its weight is reduced. <P>SOLUTION: The valve unit includes a valve member for controlling a high-pressure fluid flow, and a body 11 for partitioning an internal space having a valve insertion hole in which the valve member is disposed and internal surface of a high pressure side, having the high-pressure fluid flowing in, is cylindrically shaped, and a guide flow path 111 having the high-pressure fluid flowing into the valve insertion hole, with a through-hole having one open end on the side face of the cylindrical space of the high-pressure side of the valve insertion hole and being formed in the direction intersecting with the axial direction of the cylindrical space. The body 11 is formed of an aluminum alloy. The guide flow path 111 is inclined when viewed from the axial direction of a cylindrical space 11a relative to a normal at the opening portion of the guide flow path 111 on the internal surface of the cylindrical space 11a. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
