Abstract
A flow path member includes a gas chamber which allows inflow and outflow of gas, and a flexible member that partitions part of the gas chamber and deforms in response to pressure change in the gas chamber, wherein the flexible member has a contact section configured to abut another object, the contact section being disposed inside a regulation section in which deformation is regulated, and the contact section abuts the another object to seal the another object during at least one of depressurization and pressurization of the gas chamber.
Claims17
A flow path member comprising:
- a gas chamber which allows inflow and outflow of gas;
- and
- a flexible member that partitions part of the gas chamber and deforms in response to pressure change in the gas chamber, wherein
- the flexible member has a contact section configured to abut another object, the contact section being disposed inside a regulation section in which deformation is regulated, and the contact section abuts the another object to seal the another object during at least one of depressurization and pressurization of the gas chamber,
- wherein
- the flexible member includes a first portion that allows more gas to permeate therethrough and a second portion that allows less gas to permeate therethrough than the first portion,
- the another object has a vent hole, which is a gas distribution site, and
- the vent hole is sealed by the contact section included in the second portion.
A flow path member comprising:
- a gas chamber which allows inflow and outflow of gas;
- and
- a flexible member that partitions part of the gas chamber and deforms in response to pressure change in the gas chamber, wherein
- the flexible member has a contact section configured to abut another object, the contact section being disposed inside a regulation section in which deformation is regulated, and the contact section abuts the another object to seal the another object during at least one of depressurization and pressurization of the gas chamber, and wherein the contact section has a shielding member having high gas shielding properties per unit thickness compared with the flexible member.
A flow path member comprising:
- a gas chamber which allows inflow and outflow of gas;
- and
- a flexible member that partitions part of the gas chamber and deforms in response to pressure change in the gas chamber, wherein
- the flexible member has a contact section configured to abut another object, the contact section being disposed inside a regulation section in which deformation is regulated, and the contact section abuts the another object to seal the another object during at least one of depressurization and pressurization of the gas chamber, and
- the contact section is in contact with the another object when pressures on both surfaces of the flexible member are equal to each other.
