Plural modular fluid transfer valves |
| abstract |
Fluid transfer valves having a first and a second actuating means are functionally assembled from a common valve housing having coaxial aligned opposed inlet and outlet ports and a hollow cylindrical interior having four stepped bores, concentrically aligned on a housing cylindrical symmetry axis. A cylindrical sealing solid piston is disposed in the cylindrical deep bore of the housing. A concentric bore in the screw cap secures and provides a close linear alignment path for the sealing solid piston. The cap has multiple concentric radial apertures disposed in an interior integral cap collar, providing a flow path for fluid transfer. A concentric piston channel uniformly disposed in and around the axis of symmetry of the piston provides fluid transfer through the valve on controlled positioning of the piston. A first aperture connects the inlet port to the annular bore surrounding the piston, and a second aperture can connect the outlet port to the piston channel. n Concentric O-rings are secured in O-ring channels in the housing hollow interior and on the sealing piston exterior, providing the sealing of the fluid flow path through the valve in any piston position. The fluid transfer is controlled by slidably positioning the sealing solid piston. A three-way valve is provided by modifying the sealing solid piston and housing, providing two separately spaced piston channels on a slidable sealing piston. |
