ABSTRACT:
A cartridge valve having a cartridge valve which has no O-ring seals in critical areas of transit flow between the cartridge and the manifold. In one preferred embodiment for a sliding-type, multi-port cartridge valve, the ported sleeve in which the sliding spool is mounted has raised circumferential sealing ridges around its outer periphery where O-rings would conventionally be located. The outer peripheral surfaces of the ridges define a taper which is identical to the taper of the cavity of the manifold block into which the valve is inserted. When the valve is seated in the cavity, the peripheral surfaces of the ridges bearing against the cavity surface provide sealing between ports or sets of ports in the sleeve and the manifold block without requiring the use of O-rings. In another preferred embodiment, the ported sleeve has a smooth taper which matches and seals against a corresponding smooth tapered cavity. Fluid control functions, such as metering, may be included as inserts in one or more of the ports in the sleeve and/or may be installed in the sleeve itself between ports.
