Portion outwards sets the support zone of radial direction, and outside cylinder inner surface is fixed together with support zone, between outside cylinder and interior cylinder
Form cavity.
Preferably, the support zone longitudinal section inner face at two end expands from head to bottom and is tilted, and makes entire inner circle
The longitudinal section of column is generally c-shaped, and the support portion at such two end can preferably support outside cylinder, prevent outside cylinder in long-time service
It is deformed in journey, and the volume of support zone can be efficiently reduced, so that the weight saving of hollow piston.
Preferably, the support zone is fixed together by welding with outside cylinder inner surface.
Preferably, the hollow rolling piston of hollow rolling piston includes outer ring, inner ring, and the inner ring longitudinal section is in
E types, the left plane for the type of falling E, right plane are parallel end faces, and mid-plane is support portion, and the outer ring is cylindrical tube, described
Three sides of the type of falling E that outer ring passes through inner ring are connected on inner ring, and the biend of inner ring and the biend of outer ring are in same put down
On face.
Since the longitudinal section of inner ring is E types, sealing area is big between outer ring parallel end faces and upper and lower bearing, it is possible to provide good
Good sealing effect；Simultaneously because the reinforcing rib among outer ring can be supported by inner ring, therefore the external cylindrical surface of outer ring and slide plate
Contact position will not be generated deformation by hollow influence, and the contact surface of slide plate and outer ring remains excellent sealing, it is ensured that entire rolling
Piston can meet requirement for a long time.
Preferably, the inner ring is connected in the form of interference hot pressing by the parallel end faces of E types with support portion with outer ring.
Preferably, the inner ring is welded on by the parallel end faces of E types on the external cylindrical surface of outer ring.
Compared with prior art, the utility model has the advantage of：It is entire to rotate due to using hollow rolling piston
The weight of formula compressor of air conditioner cylinder assembly mitigates significantly, can be more energy efficient, and makes total smaller.
Due also to using the slide plate with needle roller, therefore, the abrasion of slide plate and hollow rolling piston reduces, so as to save energy
Consumption.
