Abstract

Hermetic refrigeration compressor, in particular for household refrigeration appliances, comprising control and connection means, such as a motor overload cutout (13) provided with a protective support (14), an electric motor starter (16), a terminal block (17) with related strain-relief (18), and a closing cover (27), in which some of these component parts are integrated into a single one-piece construction (15). The cover (27) is mounted slidably in a direction which is tangential to the casing (10) of the compressor. This solution is advantageous in that it cuts the number of parts to be assembled and reduces the amount of space required to accommodate the compressor.

Claims

1. Hermetic refrigeration compressor, in particular for household refrigeration appliances, enclosed in an outer casing (10) and comprising control and connection means, such as a motor overload cutout (13) provided with a protective support (14), an electric motor starter (16), a terminal block (17) and a strain relief (18) for the connection of the power supply cables, and a closing cover (27), in which al said component parts are mounted on a bracket (11) attached on to the outer wall of the compressor, and said protective support (14), said electric starter (16) and said terminal block (17) are integrated into a single one-piece construction (15), wherein said cover (27) is mounted slidably, in a direction which is tangential to the casing (10), on a first guide (28) provided on the bracket (11) and a second guide (29) provided on the strain-relief (18).

2. Hermetic refrigeration compressor according to claim 1, wherein said guides (28, 29) extend parallel to each other and are arranged horizontally on two distinct levels, in a direction which is orthogonal to the outer axis of the casing (10).

3. Hermetic refrigeration compressor according to claim 1, wherein said bracket (11) supports an auxiliary bracket (31) which the running capacitor (32) of the compressor motor is capable of being fastened to.

4. Hermetic refrigeration compressor according to claim 3, wherein said bracket (11) supports an auxiliary bracket (31) which the running capacitor (32) of the compressor motor is capable of being fastened to.
