CONNECTOR

摘要

Provided is a connector which can facilitate tuning of frequency of pulsation to be reduced and prevent sealing performance from degrading when a piston moves. A pulsation reducing member adopts a structure in which the piston moves in a cylinder. The cylinder has an annular flange portion projecting in a radially inner direction of a hollow cylindrical shape. An elastic sealing member is sandwiched in a compressed state between an end surface of the flange portion of the cylinder and an end surface of the piston. An urging body is disposed in a region in the cylinder on a side of the piston opposite to a passage and applies urging force to move the piston toward the passage and compress the elastic sealing member.

1. A connector, comprising:
a housing forming a passage for conveying fluid from one end to the other end thereof, and connecting a first member on a side of the one end with a second member on a side of the other end; and a pulsation reducing member provided on the housing; the pulsating reducing member comprising: a cylinder formed in a hollow cylindrical shape integrally with the housing, having an opening portion on one end side of the hollow cylindrical shape communicating with the passage, and having an annular flange portion projecting in a radially inner direction of the hollow cylindrical shape; a piston disposed in the cylinder on a side of the flange portion opposite to the passage and movable in the cylinder; an elastic sealing member sandwiched in a compressed state between an end surface of the flange portion and an end surface of the piston, dividing a region on a side of the piston near the passage from a region on a side of the piston opposite to the passage in the cylinder, and changing in amount of compression in accordance with position of the piston; and an urging body disposed in the region on the side of the piston opposite to the passage in the cylinder and applying urging force to move the piston toward the passage and compress the elastic sealing member.
