Title:
COMPRESSION MECHANISM OF RECIPROCATING COMPRESSOR, AND RECIPROCATING COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2018/218944
Kind Code:
A1
Abstract:
A compression mechanism of a reciprocating compressor, the compression mechanism (100) comprising a crankshaft (2), a piston (4), a crankshaft eccentric sleeve (5), and a locking mechanism. The crankshaft (2) has an eccentric part (21), and the two ends of a connecting rod (3) are respectively a crankshaft connecting part (31) and a piston connecting part (32), the crankshaft connecting part (31) being sleeved over the eccentric part (21). The crankshaft eccentric sleeve (5) is sleeved between the crankshaft connecting part (31) and the eccentric part (21). The locking mechanism is arranged between the crankshaft eccentric sleeve (5) and the crankshaft (2); when the crankshaft (2) rotates in a different direction, the locking mechanism can lock the crankshaft eccentric sleeve (5) at different angles of the crankshaft (2), so that the stroke of the piston (4) is different. The compression mechanism has a dual refrigerating capacity. Also disclosed is a reciprocating compressor.
