Abstract

An improved cylinder head-suction muffler assembly includes a suction muffler (2), a cylinder head (1), a capillary tube (7) and a self-latching clip (5). The suction muffler (2), has a suction tube (3) with a mounting block (14) and a capillary tube holder (13), and the cylinder head (1) has a suction plenum (4) and an extended portion (6) with a pair of channels (10). The self-latching clip (5) is mounted on the mounting block (14) and in the channels (10) to secure the suction muffler (2) assembly to the cylinder head (1). The self-latching clip (5) has a narrow portion (9), a wide portion (11), and a pair of bent ends (12). To couple the suction muffler (2) to the cylinder head (1) the suction tube (3) is inserted into the suction plenum (4). The capillary tube (7) is positioned in the capillary tube holder (13) and the narrow portion (9) of the self-latching clip (5) is mounted on the mounting block (14) and over the capillary tube (7) and a wide portion (11) is placed in the channels (10). The clip (5) is pushed in until the bent ends (12) are outside of the channels (10), and the clip (5) is securely in place.

Claims

1. A cylinder head-suction muffler assembly in a compressor for compressing fluids, said assembly comprising:

a cylinder head having a suction plenum and an extended portion, said extended portion having a pair of channels;

a suction muffler having a suction tube, said suction tube disposed inside said suction plenum;

a mounting block integrated with said suction tube;

a capillary tube holder for holding a capillary tube; and

a self-latching clip snugly fitted over said mounting block and fitted within said channels to prevent said suction muffler tube from being disengaged from said suction plenum without requiring a threaded fastener, said clip being made of an elastic material and having a general U-shape such that the clip can be temporarily widened to easily place the clip into position.

2. The assembly as claimed in claim 1 wherein said clip has a narrow portion, a wide portion, a shoulder, and bent ends.

3. The assembly as claimed in claim 2 wherein said narrow portion is U-shaped and has a top and sides with the sides being substantially perpendicular to said top.

4. The assembly as claimed in claim 3 wherein said wide portion has slanting sides.

5. The assembly according to claim 2 wherein said clip is a made from a flat rectangular metal strip.

6. The assembly according to claim 1 wherein said capillary tube is placed under the self-latching clip.
