LIQUID SEALED MOTOR AND PUMP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a compact liquid sealed motor capable of coping with a pressure variation caused by a temperature change of a sealed liquid.SOLUTION: The liquid sealed motor includes a sealed liquid that is sealed. The liquid sealed motor includes: a casing; an absorption mechanism, and a check valve. The casing seals the sealed liquid and is formed so that an external fluid is inhibited from intruding inside. The absorption mechanism absorbs a pressure difference between inside and outside of the casing. The check valve discharges the sealed liquid sealed in the casing toward outside.SELECTED DRAWING: Figure 2
