Linear Compressor Piston Assembly for Lateral Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear compressors face issues with lateral force damage to the piston and potential oil shortages in oil-lubricated models, which can reduce reliability and efficiency.
Innovation Solution
A compressor design that includes a piston with a rod and plate configuration, where the rod distributes lateral forces and increases refrigerant introduction through flow holes, and an elastic member to enhance structural integrity and refrigerant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rod is added to distribute lateral forces, then piston damage is reduced, but device complexity increases
Solution Approach 1:
The piston is divided into multiple functional parts: a piston body, a separate rod component, and a plate. The rod is positioned within the piston to distribute lateral forces away from the piston walls, preventing damage while maintaining structural integrity through modular segmentation.
2Productivity
If flow holes are added to increase refrigerant introduction, then compression efficiency improves, but manufacturing complexity increases
Solution Approach 1:
The plate component of the piston incorporates multiple flow holes that allow refrigerant to pass through. These holes are strategically positioned to enhance refrigerant introduction into the compression chamber while maintaining manufacturability through standard drilling and machining processes.
3Reliability
If an elastic member is added to enhance structural integrity, then piston reliability improves, but device complexity increases
Solution Approach 1:
An elastic member is integrated into the piston structure to provide flexibility and enhance structural integrity. This elastic component works in conjunction with the rigid piston body and rod to distribute stresses and improve overall reliability under varying operating conditions.

AI summary
A compressor is disclosed. The compressor compressing and discharging a refrigerant sucked into a cylinder includes a cylinder forming a compression space of the refrigerant and having a cylindrical shape; a piston configured to reciprocate in the cylinder along an axial direction and having a cylindrical shape; a suction valve disposed at a front of the piston; a plate disposed in a rear of the piston, the plate comprising a flow groove into which the refrigerant is sucked; and a rod extending along the axial direction, one end of the rod being disposed on the suction valve, and other end of the rod being disposed on the plate.
