Abstract
A modular hydraulic valve is disclosed, which comprises a valve manifold and a number of valve cartridge elements disposed at least partly within cavities defined in the valve manifold. To encourage interchangeability and reduce manufacturing costs, each cavity includes a number of axially aligned steps of progressively decreasing diameter. The outermost steps of each cavity is defined by a diameter identical with the outermost step diameter of all other cavities, regardless of whether those other cavities define one or more than one additional steps. Likewise, the second outermost step in each cavity is defined by another diameter which is substantially identical with the second step diameter of all other cavities having two or more steps.
Claims12
A modular hydraulic valve, comprising a valve manifold defining a plurality of valve cartridge-accepting cavities, and a plurality of valve elements adapted to be secured at least partly within the cavities, each cavity being defined by a plurality of concentric, axially adjacent steps of decreasing diameters extending inwardly of the manifold surface, at least one such cavity having a different number of steps than another cavity, the outermost step diameter of said one cavity being substantially identical with the outermost step diameter of said other cavity having a differing number of steps.
A manifold for a multi-function modular hydraulic valve, comprising a manifold body defining a plurality of valve cavities in and on which a plurality of valve cartridge elements can be secured, each cavity being defined by a series of concentric steps of decreasing diameter extending inwardly of the manifold surface, the outermost step diameter of one cavity being substantially identical with the outermost step diameter of at least some other cavities having a different total number of steps than said one cavity, and the second outermost step diameter of said cavity being substantially identical with the second outermost step diameter of at least some cavities having a different total of steps.
