Abstract

1400041 Compressing gases DANFOSS AS 22 Aug 1972 [7 Sept 1971 ] 39019/72 Heading F1N [Also in Division F2] In a piston compressor 3 comprising a connecting rod 13 having an end 15 with an opening 19 surrounding the crank-pin 11, the connecting rod of part of it is tiltable towards and away from the crank-pin about an axis substantially normal to a plane containing the piston axis and the crankshaft axis so that the end 15 may be swung over the crank-pin when the piston and crank-shaft are in their operative positions. In the construction shown, in which the compressor is driven by an electric motor and suspended by springs 2 in a case 1, the connecting rod 13 is connected to the piston 9 by a ball joint 14 and a packing ring 16 is fitted in the opening 19 between the end 15 and the crank-pin. To assemble the parts, the piston with the connecting rod attached is inserted in the cylinder 8 and the rod is then pivoted and tilted upwards to permit the crank-shaft to be entered into its bearing 6. The end connecting rod is then pivoted and swung downwards over the free end 12 of the crank-pin until it is in its working position, when the packing ring 16 is fitted. In the modification shown in Fig. 5, a packing ring 20 has an eccentric opening 21 for the crank-pin 11 and grooves 22 on the periphery of the ring can be aligned with a complementery groove 23 in the end 15 and secured by a pin 24 to provide means for adjusting the dead-centre position of the piston in the cylinder.
