Abstract
A reciprocating compressor includes: a cylinder forming a cylinder chamber; an intake valve disposed around the cylinder chamber; a movable part including either an intake valve seat configured to seat the intake valve or a back member located on an opposite side of the intake valve from the intake valve seat, and configured to move in an axial direction of the cylinder; and an actuator for moving the movable part in the axial direction to change a movable range of the intake valve between the intake valve seat and the back member.
Claims13
A reciprocating compressor, comprising:
- a cylinder forming a cylinder chamber;
- an intake valve disposed around the cylinder chamber;
- a piston configured to reciprocate inside the cylinder;
- an intake valve seat configured to seat the intake valve;
- a back member located on an opposite side of the intake valve from the intake valve seat;
- and
- an actuator configured to move a movable part including either the intake valve seat or the back member in an axial direction of the cylinder to change a movable range of the intake valve between the intake valve seat and the back member,
- wherein the actuator is configured to change the movable range of the intake valve during an operating cycle that includes an intake stroke, in which a gas is sucked into the cylinder chamber, and a discharge stroke, in which the gas compressed by the piston is discharged from the cylinder chamber.
A reciprocating compressor, comprising:
- a cylinder forming a cylinder chamber;
- an intake valve disposed around the cylinder chamber;
- an intake valve seat configured to seat the intake valve;
- a back member located on an opposite side of the intake valve from the intake valve seat;
- and
- an actuator configured to move a movable part including the intake valve seat in an axial direction of the cylinder to change a movable range of the intake valve between the intake valve seat and the back member,
- wherein the actuator includes:
- a moving member located on an opposite side of the intake valve seat from the back member and configured to move in the axial direction;
- and
- a cam ring located on an opposite side of the moving member from the intake valve seat and configured to rotate around an axis of the cylinder, and
- wherein the cam ring has a cam surface inclined with respect to a rotational direction and is configured such that the cam surface sliding against the moving member as the cam ring rotates moves the moving member and the intake valve seat toward the back member.
A reciprocating compressor, comprising:
- a cylinder forming a cylinder chamber;
- an intake valve disposed around the cylinder chamber;
- an intake valve seat configured to seat the intake valve;
- a back member located on an opposite side of the intake valve from the intake valve seat;
- and
- an actuator configured to move a movable part including the back member in an axial direction of the cylinder to change a movable range of the intake valve between the intake valve seat and the back member,
- wherein the back member includes an inclined surface inclined with respect to a radial direction of the cylinder, and
- wherein the actuator includes a moving member having a facing inclined surface facing and abutting on the inclined surface, and configured to move along the radial direction to move the back member in the axial direction.
