Embodiment Construction
[0040] As mentioned above and shown in the drawings, the type of refrigeration compressor to which the radial support arrangement of the present invention is applied includes a crankcase 10 inside a housing (not shown) in a one-piece or non-one-piece The form bears a support hub 40 internally delimiting a radial support 41 with axis X1 and cylinder 20 with axis Z.
[0041] A crankshaft 50 with an axis Y1 is mounted inside the radial support 41 of the support hub 40 and comprises a free end 56 and an eccentric end 55 with an axis Y2 extending from the first end of the support hub 40 A portion 40a protrudes outward, and a free end protrudes outward from a second end portion 40b of the support hub 40 .
[0042] The piston 30 is housed in the cylinder 20 so as to be moved in a reciprocating manner within the cylinder by a connecting rod 60 having an end defining a larger aperture 61 and carrying coupling means CM to allow coupling of the connecting rod 60 to the opening of the pis...
