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.
摘要:
The invention relates to a crankshaft drive, more preferably for internal combustion engines and compressors with connecting rod and piston. The connecting rod (1) is linked with the piston (2) by means of positive locking without a piston pin.

The invention relates to a method of installing and turnably journaling a connecting rod (2) to a piston (1). The piston (1) is provided with a bearing member (3) having a curved bearing surface to be turnably engaged with an end part (2a) of the connecting rod (2) provided with similar bearing surface. The bearing member (3) has a ring-like shape with a cut-out (3a) at the side of the connecting rod (2). The end part (2a) of the connecting rod (2) is arranged through the cut-out (3a) into the piston (1) in a position, in which the end part (2a) of the connecting rod (2) and the bearing member (3) are essentially perpendicular with regard to each other. Then the connecting rod (2) or the piston (1) is moved further so that the end part (2a) of the connecting rod (2) becomes in contact with the bearing member (3). Thereafter the end part (2a) of the connecting rod (2) and the bearing member (3) are arranged to their final position by means of relative turning movement between the connecting rod (2) and the piston (1) so that the mutual bearing surfaces are aligned and substantially correspond to each other.

The present invention relates to a piston (10) and a piston - connecting rod assembly (1) for internal combustion engines or compressors, featuring a pinless connecting rod assembly having a joint claw (11), the joint claw (11) is formed to partly encompass an upper joining end (12) of a connecting rod (13), whereas the joint claw (11) is formed as a part of an inner section (14) of the piston (10), and whereas the inner section (14) is radially encircled by a cylindrical piston (15). According to the invention at least one bar element (16) is arranged extending between the inner section (14) and the piston skirt (15), whereas the bar element (16) divides a first open section (17) from at least one second open section (18) being arranged between the inner section (14) and the piston skirt (15).
