AI Technical Summary

Benefits of technology

The technical effect of this patented invention is that it allows for accurate measurement of high-pressure air pressures without requiring any safety valves.

Problems solved by technology

This patent describes improving the accuracy and reliability of an air compressor used for inflating objects like tires. However, there can be issues with the current pressure display devices due to their limited measurement range and potential wear and tear caused by dust and oil stain from the air compressor's moving parts. Additionally, the existing designs have limitations in preventing excessive pressure during rapid decompression, leading to incorrect measurements and increased size requirements.

Abstract

An air compressor having a pressure gauge, the pressure gauge contains: a hollow tube, a drive element, an anti-leak spring, a resilient element, and a cap. The hollow tube includes an accommodation chamber, a connector having a conduit, and a display unit. The drive element includes a protection unit, a first open segment, a second distal segment, a receiving portion, a hollow extension, and a protrusion. An anti-leak spring is received in the hollow extension of the drive element and abuts against the protrusion and the protection unit. The resilient element is received in the receiving portion. The cap includes a seat, a push bolt, and multiple passages. The accommodation chamber has a first fixing section and a second fixing section, a diameter of which is different from that of the first fixing section. The hollow tube further includes a tilted surround section and at least one discharge orifice.
