Receiver for refrigerant apparatus

摘要

A receiver comprising a closed tank having a top wall with a planar upper surface. The top wall is formed with a blind screw bore and two refrigerant channels each having an outer end opened at the wall upper surface and an enlarged portion at the outer end. Inlet and outlet refrigerant pipes are connected to the top wall and inserted each at its one end in the respective channels. Each refrigerant pipe has an annular projection formed on its outer periphery over the entire circumference thereof and fitted in the channel enlarged portion. A fixing plate having a planar lower surface is disposed over the wall upper surface for fixing the pipes to the top wall. The fixing plate is formed with a screw hole, two circular holes each having a diameter approximately equal to the outside diameter of the annular projection for the projection to pass therethrough, and pipe inserting circular-arc cutouts extending from the respective circular holes in the same circumferential direction so as to be positioned on a circle concentric with the screw hole when seen from above and having a width not permitting the projection to pass therethrough. The fixing plate is fastened to the top wall with a screw driven through the screw hole into the blind screw bore.
