Liquid separation constituent, liquid separation filter, compressor system, and method of producing liquid separation filter having multilayer structure

A liquid separation constituent used with being attached to a top plate, the liquid separation constituent comprising:

• a second element portion having a tubular shape and including a second fiber layer that is a fiber layer for separating liquid from gas discharged from a compressor;
• an annular first attachment portion to which a first end portion of the second element portion is attached;
• and
• a second attachment portion to which a second end portion of the second element portion is attached, wherein
• a first element portion having a first fiber layer that is a fiber layer for separating liquid from gas discharged from the compressor can be attached to and detached from the top plate by a fixture,
• the first element portion includes a holding portion that holds a first end portion of the first fiber layer,
• the first attachment portion is disposed between the top plate and the first element portion in a state where restraint on the top plate by the fixture is released, and is configured to be fixed to the top plate by attachment of the holding portion to the top plate by the fixture or one of a same type as the fixture, and
• the liquid separation constituent includes an annular gasket disposed on a surface facing the top plate in the first attachment portion.

A method of producing a liquid separation filter having a multilayer structure by causing a first element portion attached to a top plate to have multiple layers,

• the first element portion including an insertion portion, an abutting portion, and a fiber layer configured to separate liquid from gas discharged from a compressor, the method comprising:
• releasing abutment of the abutting portion on the top plate by removing the insertion portion from the through hole from a state in which the insertion portion of the first element portion is inserted into a through hole formed in the top plate and the abutting portion of the first element portion abuts on a first surface of the top plate;
• preparing a liquid separation constituent including a second element portion and a first attachment portion to which a first end portion of the second element portion is attached, the first attachment portion having an annular abutting portion;
• causing the annular abutting portion to abut on the first surface of the top plate, and the abutting portion of the first element portion to abut on the annular abutting portion, so that the first element portion is covered with the second element portion;
• and
• holding the first attachment portion between the top plate and the abutting portion of the first element portion.

A method of producing a liquid separation filter having a multilayer structure by causing a first element portion attached to a top plate to have multiple layers,

• the first element portion including a fiber layer configured to separate liquid from gas discharged from a compressor, the method comprising:
• releasing fixation of the first element portion by a fixture from a state in which the first element portion is located on a first side of the top plate and the first element portion is fixed to the top plate by the fixture;
• preparing a liquid separation constituent including a second element portion and a first attachment portion to which a first end portion of the second element portion is attached;
• sandwiching the first attachment portion between the first element portion and the top plate while the first element portion is covered with the second element portion, and at this time, sandwiching an annular gasket between the first attachment portion and the top plate;
• and
• the first element portion and the top plate are fixed to each other in a state where the first attachment portion is sandwiched by the fixture or one of a same type as the fixture.
