    摘要： A crank mechanism for a reciprocating compressor is described, which can be of the double acting type or of the type provided with opposite single acting cylinders (26A, 26B). The crank mechanism is made up of a crank shaft (10) that, through a connecting rod (12), transforms its rotary motion into reciprocating motion. The connecting rod (12) receives the motion from the shaft (10) and transmits it to a cross head (14) through a jack (16). The cross head (14) is in turn, normally, made up of two shoes, a lower one (42) and an upper one (40), guided by respective fixed counter-shoes (18, 20) and transmits its reciprocating motion to the piston (22, 22A, 22B) through a rod (24). One (40) of the sliding shoes is equipped with a surface for making contact with the tracks (18, 20) having different shape and/or size with respect to the contact surface of the opposite sliding shoe (42).

    摘要： The invention relates to a compressor (1) for gaseous and/or deep-frozen liquefied media, comprising a first compressor piston (6) and a second compressor piston (7) which are drivingly connected to an eccentric shaft (2). The second compressor piston (7) is located essentially opposite the first compressor piston (6) relative to the eccentric shaft (2). The aim of the invention is to render such a compressor compact and keep the effort for building the same low. Said aim is achieved by embodying the compressor (1) as an oscillating piston-type compressor in which the first compressor piston (6) is disposed on an eccentric ring (4) that is effectively connected to the eccentric shaft (2), while the second compressor piston (7) is fastened to a pivot lug (8) that is effectively connected to the eccentric ring (4).

    摘要： Crank gear (10) for a reciprocating compressor of the type equipped with at least one module which has two lines with two opposite cylinders. The crank gear is suitable for constraining the two cylinders to a crankshaft (20), so as to align the two cylinders, opposite each other with respect to an axis (21) of the shaft (20). The crank gear (10) is equipped with two rods (35), a series of connecting rods (30) and two cross heads (40) and (50). The series of identical connecting rods (30) is symmetrically positioned with respect to the alignment axis (25) of the two cylinders and furthermore the overall barycentre of the series of connecting rods lies on the axis (25) and on the axis (21) of the shaft (20) so that the whole of the shaft (20) is both statically and dynamically balanced.

    摘要： The invention relates to a piston arrangement for a dual-stage piston compressor, comprising a crankshaft and several cylinders which house the operating pistons. Said arrangement allows two or more low-pressure stages and at least one high-pressure stage to be formed. The invention is characterised in that the two or more low-pressure cylinders are arranged in relation to the high-pressure stage in such a way that said two or more low-pressure cylinders are in phase or are offset by less than +/- 15 DEG and compress in a position which is offset by 180 DEG +/- 20, in relation to one or more high-pressure cylinders.

    摘要： The invention concerns a vacuum pump comprising two cylinders (1, 2) wherein the respective pistons (3, 4) define respective volumes (V1, V2) which increase during the suction phase and decrease during the discharge phase. The invention is characterised in that the cylinders (1, 2) are symmetrically aligned with each other relative to the main axis X, and the pistons (3, 4) are driven, for example by a cam (5), such that the suction phase, which corresponds to an angular rotation A1 of the cam, lasts longer than the discharge phase, which corresponds to an angular rotation A2 of the cam.
