FLUID MACHINERY
Document Type and Number:
Japanese Patent JP2017172503
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid machinery capable of making a small-sized closed vessel and a thin-walled formation of the vessel while assuring a pressure resistance and airtightness of the closed vessel, capable of attaining a small-sized formation of a sealed terminal and improving mountability and reliability while realizing a light-weight formation and a small-sized formation.SOLUTION: A sealed terminal 18 for relaying a supplying of electricity from an external part of a closed vessel 2 to an electric motor 4 comprises: a terminal pin 44; a terminal main body 42 fitted to a welding hole 20 through which the terminal pin 44 passes; and an insulation seal part 46 interposed between the terminal pin 44 and the terminal main body 42 and having an inner peripheral seal surface 46b closely contacted with the inside of the terminal main body 42. The terminal main body 42 comprises: a main body part 42a formed with the inner peripheral seal surface 46b and positioned to be overlapped with the welding hole 20 in an axial line direction X of the terminal pin 44; and an end part 42b extending from the main body part 42a to inside of the closed vessel 2 and formed with a welding part 48, the welding part 48 and the inner peripheral seal surface 46b are positioned to be spaced apart in the axial line direction X.SELECTED DRAWING: Figure 1
