AI Technical Summary

Benefits of technology

The present invention is a variable compression system that can detect and control the slant angle of a slant plate with more precision and speed. This system can quickly calculate the torque required for the refrigerant compressor and adjust the angle of the slant plate to achieve optimal performance. A position detecting sensor is used to precisely locate the position of the guiding shaft, which is controlled by the slant plate and the slant control shaft. Overall, this technology allows for more precise and efficient control of the compression process in refrigerant compressors.

Problems solved by technology

Consequently, calculation of a torque required for operation of the refrigerant compressor is difficult, to fail precise control of the refrigerant compressor, resulting in failure in optimization of fuel consumption efficiency.

Abstract

A variable compression system for controlling a slant angle of a slant plate may include a rotation plate, the slant plate coupled to one side of the rotation plate, a compression piston connected to an edge of the slant plate, a slant control shaft connected to a center of the slant plate with a variable pin arranged to rotate with the slant plate for pushing or pulling the slant plate by a hydraulic pressure being supplied thereto to control the slant angle of the slant plate, a position guiding shaft arranged passed through a center portion of the slant control shaft, a position detecting sensor engaged to the position guiding shaft for detecting a position of the position guiding shaft, and a control unit for determining the slant angle of the slant plate with reference to a signal from the position detecting sensor.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2013-0167814 filed on Dec. 30, 2013, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a variable compression system for controlling a slant angle of a slant plate to control a reciprocating range of a piston for controlling a load of refrigerant compression, and sensing the slant angle of the slant plate, easily.[0004]2. Description of Related Art[0005]A compressor applied to a vehicle is a variable capacity compressor which has suction and discharge rates controlled by a control valve and the slant plate mounted in the compressor, automatically.[0006]Since a major feature of the variable capacity compressor lies on variable control of a flow rate of the refrigerant throughout an entire operation range of a cooling load of an air co...
