Valve connector

A valve connector, comprising:

• a connector housing having a through-path, the connector housing being provided with a tube connecting portion on one axial end thereof and a pipe inserting portion on the other axial end thereof,
• an internal valve disposed in the connector housing for opening and closing the through-path, the internal valve having a valve seat surface defined in the connector housing, a valve body including a closing portion with an abutting surface for abutting with the valve seat surface on an outer peripheral portion of the closing portion, and a compression spring biasing the valve body toward the valve seat surface, the valve body being housed in the connector housing movably in an axial direction,
• the valve body further having a plurality of guides extending from the closing portion in a direction away from the valve seat surface, which are disposed spaced apart in a circumferential direction so as to slide on an inner peripheral surface of the connector housing, the guide having a support recess to extend in the axial direction, a radially inward portion on a radially inward end of the guide with respect to the support recess, and a radially outward portion on a radially outward end of the guide with respect to the support recess,
• one axial end portion of the compression spring being received in the support recess, and the other axial end portion thereof being supported in a spring bearing formed on a side of the connector housing, and
• the radially inward portion extending longer than the radially outward portion in the direction away from the valve seat surface.
