Claim 1
Independent Claim
240 words
A valve base for connecting hydraulic valves in hydraulic circuits, comprising a body (affording) having a number of longitudinal channels extending end to end through it, said channels having coplanar axes (with their axes coplanar,) for the supply and return of a hydraulic fluid and for other hydraulic connections from the valves, groups of holes in said body and each in a (standardised) predetermined pattern to fit a (standardised) predetermined pattern of connections of a hydraulic valve, said groups of holes communicating with respective channels a transverse bore associated with each group of holes and intersecting all the longitudinal channels, (and in each transverse bore,) a column of distributor elements in each transverse bore and (modules which are) held in the bore by terminal members at the ends of the transverse bore, one distributor (module) element being located at each intersection of the transverse bore with each longitudinal channel, said distributor elements interconnecting predetermined channels for forming a predetermined hydraulic circuit, a solid spacing disc forming a partition blocking said transverse bore, at least one of said terminal members having in it an opening in alignment with axial bores of said distributor element and adapted for connection of a pipe thereto, each transverse bore being located at an intermediate position in the portion of the length of the body containing the respective group of holes, said spacing disc being located between each pair of neighboring distributor elements in a column.
