Liquid level detector for high hydraulic pressure circuit
专利汇可以提供Liquid level detector for high hydraulic pressure circuit专利检索，专利查询，专利分析的服务。并且PURPOSE: To easily detect a liquid level from outside by providing a float to which a magnet is fitted in an air collection chamber, and detecting the magnetic flux of the magnet by a magnetic sensor without affecting the reliability of oil- and air-tightness.
CONSTITUTION: Air bubbles produced in the hydraulic pressure circuit are collected at the upper part of the air collection chamber 1 and the gas space 5 expands, so that the liquid level of working liquid 4 drops. When the float 7 moves down accordingly, the magnet 9 also moves down in a pipe 3. Then when the magnet 9 reaches the sensing range of the magnetic sensor 10, the contact of the magnetic sensor 10 operates, and consequently the presence of the liquid level in the air collection chamber 1 at a specific position is detected and led out as an electric signal through a lead line 11. Therefore, a valve 12 is opened only when the magnetic sensor 10, securely performing necessary gas discharge. Thus, the liquid level is easily detected from outside the air collection chamber 1 and oil-tightness, airtightness, and high reliability are obtained.
