Abstract
A valve connector includes a body having a first end adapted to attach to an American valve, a second end opposite the first end, and a through hole extending through both ends. A shoulder portion divides the through hole into a first accommodating portion and a second accommodating portion, with a sealing ring disposed on the second accommodating portion. A control member is movably disposed in relation to the body between a first and second position. The control member includes a body portion, a guiding hole, an abutting end, and a control end adapted to communicate with an air pump device. A venting portion is arranged between the abutting end and the control end, having a first cross-sectional area smaller than a second cross-sectional area.
Claims9
A valve connector, comprising:
- a body having a first end adapted to attach to an American valve, a second end opposite to the first end, and a through hole extending through the first end and the second end, wherein a shoulder portion is formed on an inner surface of the through hole to divide the through hole into a first accommodating portion and a second accommodating portion, and wherein a sealing ring is disposed on an inner surface of the second accommodating portion of the through hole;
- and
- a control member axially movable in relation to the body between a first position and a second position, wherein the control member includes a body portion and a guiding hole formed in the body portion and communicating with the through hole, wherein one end of the body portion forms an abutting end, and the other end of the body portion forms a control end exposed at the second end and adapted to communicate with an air pump device, wherein the guiding hole provides an air passage between the abutting end and the control end to allow air communication between the through hole and the air pump device, wherein the body portion has a venting portion arranged between the abutting end and the control end, and wherein the venting portion has a first cross-sectional area at an end thereof adjacent to the abutting end less than a second cross-sectional area at an end thereof away from the abutting end;
- wherein when the control member is in the first position, the sealing ring is disposed between the venting portion and the control end and abuts against an outer surface of the body portion, the abutting end passes through the annular shoulder and enters the first accommodating portion to abut against a valve core of the American valve;
- wherein when the control member is in the second position, the sealing ring is disposed between the venting portion and the abutting end and is separated from the outer surface of the body portion, the abutting end exits the first accommodating portion.
