Damping piston

Abstract

The invention discloses a damping piston. The damping piston comprises a piston body which is of a hollow structure, a first through hole is formed in the piston body, a squeezing column is movably arranged in the first through hole, and moreover the squeezing column extends out of the piston body; a threaded pipe is arranged on the bottom end of the inner wall of the piston body, the side, far away from the bottom end of the inner wall of the piston body, of the threaded pipe is arranged on the squeezing column, a gas storage tank is arranged on the bottom end of the inner wall of the piston body, and moreover the gas storage tank is arranged at one side of the threaded pipe; and a gas pipeline is arranged on side, close to the threaded pipe, of the gas storage tank, the end, far away from the gas storage tank, of the gas pipeline is connected to the threaded pipe, a first electric valve is arranged on the gas pipeline, and the side, far away from the gas storage tank, of the threaded pipe is provided with a gas outlet pipeline. According to the damping piston, the structure is novel, the impact force suffered by the piston body can be buffered, the gas pressure in the threaded pipe can be increased or reduced automatically at the same time, the buffer force of the threaded pipe is ensured, and the usage demands of people are met.

Description

technical field [0001] The invention relates to the technical field of pistons, in particular to a damping piston. Background technique [0002] The piston is a reciprocating part in the cylinder block of an automobile engine. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected form of the combustion chamber. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat-absorbing areas. There are often various pits on the top of the piston of a diesel engine, and its specific shape, position and size must be adapted to the requirements of the mixture formation and combustion of the diesel engine. However, most of the existing pistons are not equipped with a damping structure, the mechanical wear is relatively large, and the service life is short, which increases people's use costs and cannot meet people's use needs.
