Abstract
The utility model relates to a piston supporting ring of a gas compressor. The tubular ring body is provided with a plurality of grooves and an inclined fracture. The grooves can be parallel or unparallel to the axis of the ring body. The piston supporting ring of the gas compressor can be sleeved at the outer side of a piston, thus avoiding the direct friction of the piston and a cylinder chamberand prolonging the service life of the piston.
Description
Technical field
The utility model relates to a kind of gas compressor piston support ring.
Background technique
On the piston of gas compressor piston ring is installed, reaches the purpose of sealing by the interior wall friction of piston ring and cylinder chamber.For the bigger cylinder chamber of diameter, the diameter of piston ring is also big, because the thickness of piston ring is limited, is easy in the time of piston motion directly rub with cylinder chamber, causes the excessive wear of piston and scraps in advance.
Summary of the invention
The purpose of this utility model provides a kind of gas compressor piston support ring that can avoid piston directly to rub, increase the service life with cylinder chamber.
For achieving the above object, the utility model is by the following technical solutions:
Gas compressor piston support ring described in the utility model is characterized in that: the fracture that has a plurality of grooves and an inclination on the ring body of tubulose.
The parallel axes of described groove and ring body.
The axis of described groove and ring body is not parallel.
Sidewall relative with fracture on the ring body is provided with through hole.
After adopting technique scheme, this gas compressor piston support ring can be sleeved on the outside of piston, avoid piston directly with working life of cylinder chamber friction, prolongation piston.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is a kind of embodiment's of the utility model a transverse sectional view;
Fig. 3 is a kind of embodiment's of the utility model a lateral plan.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in drawings, gas compressor piston support ring described in the utility model has the fracture 2 of a plurality of grooves 3 and an inclination on the ring body 1 of tubulose.Described groove 3 is out the straight trough on ring body 1 outer wall, groove 3 can with the parallel axes of ring body 1, also can be not parallel.The effect of groove 3 is to connect two ends up and down, and oil, gas can circulate by groove 3 in the time of pistons work,
The setting of fracture 2 makes ring body 1 have certain elasticity, can very closely be sleeved on the outside of piston.
In addition, in order to reduce friction, sidewall relative with fracture 2 on the ring body 1 is provided with through hole 4.
During use, gas compressor piston support ring described in the utility model is sleeved on the piston, is positioned at the two ends up and down of piston ring, can avoid like this piston directly with working life of cylinder chamber friction, prolongation piston.
