Abstract

Described is a stopper including a filtering unit housed in an interior of a liquid receiver main body through which a refrigerant passes, a fixed portion that includes a screw portion that is screwed into an inner peripheral face of the liquid receiver main body, a sealing member in contact with the inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion, and a movable connection portion provided between the filtering unit and the fixed portion for linking the filtering unit to the fixed portion in such a way that the filtering unit is not caused to follow a rotation of the fixed portion, and in such a way that the filtering unit is caused to follow an axial direction movement of the fixed portion.

First claim

What is claimed is:

1. A liquid receiver, comprising:
a liquid receiver main body that is formed in a tubular form and stores a refrigerant in an interior; and
a stopper that is inserted into a one side aperture portion provided in a one side end portion in a longitudinal direction of the liquid receiver main body, thereby blocking off the one side aperture portion, wherein the stopper includes
a filtering unit that is housed in the interior of the liquid receiver main body and through which the refrigerant passes,
a fixed portion that includes on an outer peripheral face thereof a screw portion that is screwed into an inner peripheral face of the one side aperture portion of the liquid receiver main body,
a sealing member that is brought into contact with an inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion from between the filtering unit and the liquid receiver main body, and
a movable connection portion that is provided between the filtering unit and the fixed portion and links the filtering unit to the fixed portion in such a way that the filtering unit is not caused to follow a rotation of the fixed portion, and in such a way that the filtering unit is caused to follow an axial direction movement of the fixed portion,
wherein the filtering unit is an injection molded article, and has a bearing face that supports the sealing member, and the bearing face is formed in a position deviating from a partitioning line of dies that mold the filtering unit.

2. The liquid receiver according to claim 1 , wherein the stopper has an intermediate portion between the filtering unit and the fixed portion, the intermediate portion is fixed with respect to the filtering unit and is linked to the fixed portion via the movable connection portion, and the sealing member is provided between the filtering unit and the intermediate portion.

3. The liquid receiver according to claim 2 , wherein the stopper further includes another sealing member that is brought into contact with the inner peripheral face of the liquid receiver main body, thereby preventing a leakage of a refrigerant to the fixed portion from between the intermediate portion and the liquid receiver main body, and the other sealing member is provided between the intermediate portion and the fixed portion.

4. The liquid receiver according to claim 3 , wherein the intermediate portion is an injection molded article, and has a bearing face that supports the sealing member and another bearing face that supports the other sealing member, and the bearing face and the other bearing face are formed in positions deviating from a partitioning line of dies that mold the intermediate portion.

5. The liquid receiver according to claim 1 , wherein the sealing member comes into contact with a stepped portion formed on the inner peripheral face of the liquid receiver main body, and is compressed in an axial direction.

6. The liquid receiver according to claim 5 , wherein the stepped portion is configured to have a tapered face.

7. A vehicle-use air conditioning device condenser including the liquid receiver according to claim 1 .
