Configurable modular sleeve valve

Abstract

A modular sleeve valve apparatus can include a valve body including a first port and a second port on a first and second sidewall of the valve body. The apparatus can include a first and second valve core sleeved within the valve body. The first valve core can be a cylinder including a first aperture in a cylindrical sidewall and a second aperture in a top base-wall. The second valve core can be a cylinder including a third aperture in a cylindrical sidewall and a fourth aperture in a bottom base-wall. The first and second valve cores can be removable from the valve body and radially rotatable within the valve body. The second valve core can be positioned stacked upon the first valve core to align the second aperture and the fourth aperture.

What is claimed is: 
     
         1 . A modular sleeve valve apparatus comprising:
 a valve body including a first port on a first sidewall of the valve body and a second port on a second sidewall of the valve body; and   a valve core sleeved within the valve body, the valve core a cylinder including a first aperture and a second aperture in a cylindrical sidewall of the valve core, the cylindrical sidewall defining a space within the valve core, the valve core removable from the valve body and radially rotatable within the valve body.   
     
     
         2 . The apparatus of  claim 1 , wherein.
 the valve core is radially rotatable between at least first position and a second position; and   wherein, when the valve core is in the first position, the first aperture is aligned with the first port and the second aperture is aligned with the second port, allowing access from the first port and second port to the space, and, when the valve core is in the second position, the first aperture is unaligned with the first port and the second aperture is unaligned with the second port.   
     
     
         3 . The apparatus of  claim 1 , wherein:
 the valve core further includes:
 a third port on a top base-wall of the valve core, the third port allowing access to the space. 
   
     
     
         4 . The apparatus of  claim 1 , wherein the valve body further includes:
 a cap base-wall, removable from the valve body, the cap base-wall securing the valve core in the valve body when attached to the valve body and allowing removal of the valve core when removed from the valve body.
