Patent ID: 7607639

Claim:
A valve apparatus comprising: a hollow cylindrical housing having an external ring surface, said external ring surface having a snapping hole formed on opposite sides thereof; a control shaft extending axially into said housing, said control shaft having a top end extending outwardly of a top of said housing so as to form a control switch, said control shaft having a bottom fitted with a filler rod; a switching component formed of ceramic material, said switching component positioned in said housing, said switching component having a groove formed on an upper side thereof so as to receive said filler rod therein, said switching component having a sectorial first water guide portion and a sectorial second water guide portion in spaced and sealed relation; a fixed hole member formed of ceramic material, said fixed hole member being coupled to said switching component, said fixed hole member having a sectorial first punch hole and a sectorial second punch hole formed opposite to each other said fixed hole member having a locating slot formed on opposite sides of an outer periphery thereof; a stationary base fixedly mounted onto one end of said housing, said stationary base having a first through hole and a second through hole formed therein so as to be respectively aligned with said first punch hole and said second punch hole of said fixed hole member, said stationary base having a splayed watertight gasket positioned on a top and a bottom thereof, said stationary base having a snapper extending upwardly on opposite sides thereof, said snapper extending through said locating slot of said fixed hole member and engaging said snapping hole of said housing, said watertight gasket at said top of said stationary base forming a seal with a bottom of said fixed hole member, said first water guide portion and said second water guide portion being linked by a coupling portion so as to form a sectorial groove extending for more than 180°, said control switch being rotatable to a closed water flow position in which a recessed space formed by said first and second water guide portions and said coupling portion does not cover both of said first and second punch holes and said sealed compartment covers said second punch hole, said control switch being rotatable to another position such that said switching component drives said second water guide portion so as to cover said second punch hole such that said first punch hole is linked to said second punch hole by said first water guide portion and said coupling portion and said second water guide portion.
