- 대표 독립항:
1. A valve assembly comprising: a valve body including a partition formed therein, the partition having a through hole at an upper side thereof and dividing an inside space of the valve body into a first internal channel and a second internal channel, a first entrance disposed adjacent to the first internal channel for supplying a fluid from the first internal channel to an outside or a fluid from the outside to the first internal channel, and a second entrance disposed adjacent to the second internal channel for supplying a fluid from the second internal channel to an outside or a fluid from the outside to the second internal channel; a first check roller and a second check roller received in the first internal channel and the second internal channel, respectively, and configured to be in contact with or separated from the through hole by buoyancy in a fluid in the first internal channel and the second internal channel according to inclination directions of the valve body; and a restrictor configured to prevent the first check roller and the second check roller from being in contact with the first entrance and the second entrance by buoyancy or flow of the fluid in the first internal channel and the second internal channel, wherein the restrictor comprises a pair of plate-shaped stoppers extended downward from a ceiling of the valve body between the first check roller and the first entrance and between the second check roller and the second entrance, respectively.

1. A test device for testing electric properties of an object, the test device comprising: an object support unit configured to support an object; a cover unit comprising a cover body coupled to the object support unit and a pusher supported by the cover body so as to move toward and away from the object upon operation; and a pressure adjuster comprising a multi-stage adjusting cam which is rotatably coupled to the cover body and configured to move the pusher upon rotation, and the multi-stage adjusting cam has a cam surface with contact radii varied depending on rotated angles so that the pusher can be positioned at a plurality of pressing positions with respect to the cover body for pressing the object, and an operation unit which operates the multi-stage adjusting cam, wherein the cam surface of the multi-stage adjusting cam includes a plurality of arcuate surface regions, and a plurality of flat surface regions between the arcuate surface regions, and the flat surface regions are configured as designated stop positions to move the pusher to a preset distance, wherein the designated stop positions include a first stop position not for pressing the object, and a second stop position and a third stop position for pressing the object, the third stop position configured to press the object to a distance less than that of the second stop position.
