Title:
RECIPROCATING POWER ASSEMBLY AND PUMP MECHANISM
Document Type and Number:
WIPO Patent Application WO/2024/093343
Kind Code:
A1
Abstract:
A reciprocating power assembly and a pump mechanism. The reciprocating power assembly (100) comprises reciprocating units (110), a linkage shaft (120), and a power unit (130). Two reciprocating units (110) are provided, reciprocating shafts (111) of the two reciprocating units (110) are respectively connected to two ends of the linkage shaft (120), and a transmission member (132) of the power unit (130) is transmittingly connected to the linkage shaft (120). When a power source (131) drives the transmission member (132) to drive the linkage shaft (120) to rotate, the reciprocating shafts (111) at the two ends can be simultaneously driven to rotate. By using reciprocating guide rails (113) on the reciprocating shafts (111), reciprocating members (112) can reciprocatingly move between a wave crest and a wave trough under the guide action of the reciprocating guide rails (113) having a curved trajectory, and the transmission stability is good. Furthermore, when the reciprocating members (112) drive plungers (220) to reciprocatingly move, a fluid is suctioned into volume cavities (211) by means of first channels (212), and is discharged from second channels (213). According to the reciprocating power assembly (100) and the pump mechanism (10), simultaneous reciprocating motion of the reciprocating members (112) of the two reciprocating units (110) is realized by means of one power source (131) and one linkage shaft (120), so that the transmission efficiency is higher, and the transmission structure is more compact.
