Abstract

A channel selecting valve has: a main body, two control cores, two stopping members, and two handles. The main body has an intake opening on one side, and a first outlet opening, a second outlet opening, a third outlet opening and a fourth outlet opening on another side. The main body connects the intake opening with each outlet opening. Two openings at each end of the main body respectively accept a control core for assembly. Each control core is a hollow tube with one open end and one closed end, the open end of the control core is inserted into one of the openings of the main body. Each of the closed ends of the control cores is connected to a respective handle for switching. Both of the two control cores have a first through hole, a second through hole, a third through hole and a fourth through hole.

First claim

What is claimed is:

1 . A channel selecting valve comprising: a main body, two control cores, two stopping members, and two handles, wherein:
the main body comprises an intake opening on one side, and a first outlet opening, a second outlet opening, a third outlet opening and a fourth outlet opening on another side, the main body connecting the intake opening with each outlet opening; two openings at each end of the main body respectively accept a control core for assembly; the main body further comprises an internal raised portion at a center position for securing the control cores and limiting rotation of the control cores; and each control core is a hollow tube with one open end and one closed end, the open end of the control core is inserted into one of the openings of the main body, an engagement between the stopping member and the opening preventing the control core from detaching; each of the closed ends of the control cores is connected to a respective handle for switching; both of the two control cores have a first through hole, a second through hole, a third through hole and a fourth through hole, the first through hole and the second through hole are separated from each other in an axial position but are radially opposed to the third through hole and the fourth through hole, and the third through hole and the fourth through hole are set at a same axial position.

2 . The channel selecting valve as claimed in claim 1 , wherein the channel selecting valve is made of plastic.

3 . The channel selecting valve as claimed in claim 1 , wherein the intake opening is connected to a fitting extending from the main body.

4 . The channel selecting valve as claimed in claim 1 , wherein all of the first outlet opening, the second outlet opening, the third outlet opening, and the fourth outlet opening are respectively connected to a connecting pipe extending from the main body.

5 . The channel selecting valve as claimed in claim 4 , wherein each of the connecting pipes respectively has a trumpet-shaped gasket and an inner piston.

6 . The channel selecting valve as claimed in claim 1 , wherein the open end of each control core further has a limiting stopper corresponding to the raised portion of the main body, for limiting rotation of the control core.

7 . The channel selecting valve as claimed in claim 1 , wherein each of the control cores is jacketed with a sealing ring.

8 . The channel selecting valve as claimed in claim 1 , wherein the stopping member is a locking nut configured to be secured onto the opening of the main body.
