DEVICE FORMED IN STRUCTURE ELIMINATING PRESSURE REGULATOR, CAPABLE OF FEEDING COOLING WATER TO RADIATOR BY UTILIZING PRESSURE OF COMPRESSOR, AND CAPABLE OF SAFELY INSPECTING LEAKAGE OF COOLING WATER WHILE ENGINE IS RUNNING AND MEASURING VARIATION IN RISE OF PRESSURE OF COOLING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a device so formed that the pressure regulator can be eliminated, safely used for a pressure test for cooling water while the engine is running, and capable of measuring the rise of the pressure of the cooling water. SOLUTION: This device utilizes the pump action of a radiator test instrument not requiring the pressure regulator in the request of Japanese Utility Model Application No. 36728/2005, installed at the top of a pressure water tank 5, and feeds air from a compressor to the pressure water tank to push up the cooling water to a radiator. By sharing a commercial cap 11 with pressure bleeding between a safety valve and the decompression device of the pressure water tank, the state of the rise of the pressure of a cooling system is measured with a pressure gauge 14 while protecting the cooling system against an excessive pressure while the engine is running.
