Kind Code:
A1
Abstract:
Disclosed are a pump body structure, a compressor, and a heat exchange apparatus. The pump body structure comprises: an air cylinder assembly (10) comprising an air cylinder (11), a piston (20) movably arranged inside the air cylinder (11), and a transmission structure (40) and a driving portion (30), wherein the transmission structure (40) is in driving connection with the piston (20); a peripheral wall of the piston (20) has guide rail grooves (21) connected end-to-end in a circumferential direction, and the air cylinder (11) has guide structures (111) extending into the interiors of the guide rail grooves (21); or an inner surface of the air cylinder (11) has the guide rail grooves (21) connected end-to-end in the circumferential direction, and the piston (20) has the guide structures (111) extending into the interiors of the guide rail grooves (21), such that, by means of driving the piston (20) by the driving portion (30), the piston (20) reciprocates inside the air cylinder (11) along a pivotal axis of the piston (20) while rotating relative to the air cylinder (11).
