摘要： Electric compressor comprising a piston provided with a connecting rod (4), an annular element arranged at an end portion thereof, a gudgeon pin, an elastic means (6) that elastically locks said gudgeon pin in the piston. The connecting rod, said annular element and said gudgeon pin are made in a one-piece construction, and said piston has no through-passing holes to accommodate the end portions of said gudgeon pin. A recess (3) in the piston is adapted to accommodate the contiguous portion of said annular element and said gudgeon pin. The elastic means has a curved contour and, together with said extensions, forms such a shape that, when applied between appropriate engaging provisions of the piston and the extensions, a rolling contact occurs between said extensions and the elastic means.
