Abstract
A first pipe, a second pipe and a third pipe are airtightly connected with each other. A cam member rotates about a rotation axis for moving a valve body so as to open/close the first pipe and the second pipe so that the third pipe is selectively communicated with the first pipe and the second pipe, the cam member being movable in a direction parallel with the rotation axis. A cam actuator drives the cam member so as to move the cam member in the direction parallel with the rotation axis to open both of the first pipe and the second pipe, when the cam member is rotated at a predetermined angle.
Claims9
A valve driving apparatus, comprising:
- a first pipe, a second pipe and a third pipe, which are airtightly connected with each other;
- a valve body;
- cam member, which rotates about a rotation axis for moving the valve body so as to open/close the first pipe and the second pipe so that the third pipe is selectively communicated with the first pipe and the second pipe, the cam member being movable in a direction parallel with the rotation axis;
- and
- a cam actuator, which drives the cam member so as to move the cam member in the direction parallel with the rotation axis to open both of the first pipe and the second pipe, when the cam member is rotated at a predetermined angle.
A valve driving apparatus, comprising:
- an inflow pipe;
- an outflow pipe;
- a casing body having an airtight chamber formed with openings respectively communicated with the inflow pipe and the outflow pipe;
- a valve body;
- a cam member, which provides an urging force on the valve body in such a direction that the valve body closes at least one of the openings;
- a cam driver, which provides a driving force for rotating the cam member;
- and
- a cam actuator, which moves the cam member against the urging force such that the openings are simultaneously opened.
