Patent Images
1. A diaphragm-type vacuum pump comprising:
- an inclined pin that is radially spaced at a predetermined distance from the rotational center of a motor and is configured to rotate around the rotational center;
a rolling plate that is connected with the inclined pin and is configured to eccentrically move up and down; and
a three-point diaphragm that is combined with the rolling plate and disposed between a diaphragm guide and an air port,wherein vacuum pumping is applied by repeating intake and exhaust processes according to changes in the internal volume of the three-point diaphragm.

Abstract
The present invention relates to a diaphragm-type vacuum pump that is compact in size and manufactured at low cost and includes an inclined pin that is radially spaced at a predetermined distance from the rotational center of a motor and turns around the rotational center, a rolling plate that is connected with the inclined pin and eccentrically shakes up and down, and a three-point diaphragm that is combined with the rolling plate and changes the internal volume by eccentrically shaking up and down, in which vacuum pumping is applied by repeating intake and exhaust of air according to changes in the internal volume of the three-point diaphragm.
