Abstract

A switchable bidirectional core-actuated valve is provided with a chamber, and a first shaft hole, a second shaft hole and an output hole communicating with the chamber. The chamber is received therein with a non-return valve able to move in the chamber. Thus, water cooling liquid can make use of water pressure to have the non-return valve moving to a first position or a second position. When the non-return valve is at the first position, the first shaft hole will communicate with the output hole, when at the second position, the second shaft hole will communicate with the output hole. Thus, water cooling liquid can get into the chamber through the first shaft hole or the second shaft hole and then flow out of the output hole.

Dependent claims

A switchable bidirectional core-actuated valve comprising:

a main body formed with a chamber, said chamber comprising a first shaft hole and a second shaft hole and an output hole communicating with one another;
a non-return valve received in said chamber, said non-return valve comprising a core-actuating member, said core-actuating member having two ends respectively provided with a damping member corresponding to said first shaft hole and said second shaft hole, said non-return valve able to move in said chamber and defined to have a first position and a second position, said damping member sealing said second shaft hole, while said first shaft hole communicating with said output hole when said non-return valve is at the first position, said damping member sealing said first shaft hole, while said second shaft hole communicating with said output hole when said non-return valve is at the second position;
and
wherein said first shaft hole and said second shaft hole are respectively inserted therein with a positioning stopper head, each said stopper head formed with a first end and a second end, an insert hole formed between said first end and said second end, each said positioning stopper head having an outer circumferential wall provided with a stopping member at a location of said first end, an external diameter of said stopping member being larger than an internal diameter of both said first shaft hole and said second shaft hole so that said stopping member can be respectively stopped at said first shaft hole and said second shaft hole, each said stopper head having an outer circumferential wall provided with a recessed groove beside said stopping member, said recessed grooves respectively mounted with a sealing ring, said insert hole provided with a stopping section at a location of said first end, an internal diameter of said stopping section being larger than an internal diameter of said insert hole, said insert hole formed with a position-limiting section beside said stopping section, said position-limiting section being smaller than said insert hole in internal diameter, said insert hole further provided with a positioning section at a location of said second end, said positioning section being larger than said insert hole in internal diameter, a diameter enlarged section disposed between said positioning section and said insert hole, said diameter enlarged section having an internal diameter gradually increased toward said second end.
