<p>PURPOSE: To prevent the disturbance of a line by providing both a valve cap fixed to the end part provided with the bored end parts of the valve body for axially closing the bored end parts and a pin stopping means axially projected in the reverse direction of the inlet port. CONSTITUTION: A valve 34 is slidable in the interior of the bored hole in the axial direction and normally closes the inlet port 22. A valve cap 14 is fixed to the end parts provided with the bored end parts 52, 54 of a valve body 12 to axially close the bored end parts 52, 54. A pin stopping means 42 is penetrated through the valve cap 14 and is axially projected in the reverse direction of the inlet port 22. Thus, the piston seal can be reset from the exterior with regard to the valve cavity, so that the disturbance of the line can be prevented during the period of the reset.</p> |
