Connection element for construction of a base plate for hydraulic devices

Claim 2

A connection element for pressure fluid devices comprising a substantially prism shaped block having two opposite substantially parallel end faces and two opposite mounting faces extending between and substantially normal to said end faces, said block being formed with five channels extending from one to the other of said end faces and having open ends on each of said end faces symmetrically arranged with respect to two axes which are normal to each other, the open ends of four of said channels being arranged at each of said end faces at the corners of a rectangle and the open ends of the fifth channel being arranged at the center of the rectangle and adapted to be connected to a pressure fluid supply, said block being further provided with openings for fastening said block to another connection element and said fastening openings being arranged symmetrically with respect to said two axes; and including four cross bores having outer open ends located at one of said mounting faces for connection to a valve, the inner end of one of said four cross bores communicating with said fifth channel and the remaining three of the four cross bores communicating with three of the other channels of which two have open ends at one of the longer sides of said rectangle, and two further cross bores having outer ends at the other mounting face for connection to external utilization circuits and communicating at the inner ends thereof with said two channels.

Claim 3

A connection element as defined in claim 1, wherein said block is provided with two pairs of flanges respectively projecting to opposite sides of said end faces, said fastening openings being provided in said flanges.

Claim 4

A base plate for pressure fluid devices comprising a plurality of connection elements, each of said connection elements comprising a prism-shaped block having a pair of end faces and being formed with five channels extending between said end faces, said channels having on each of said end faces open ends symmetrically arranged with respect to two axes which are normal to each other and the open ends of four of said channels being respectively located at each of said end faces at the corners of a rectangle and the open end of the fifth channel being located at the center of the rectangle, said plurality of connection elements being arranged abutting with said end faces thereof against each other and with said channels respectively aligned with each other, at least some of said prism shaped connecting elements having opposite muounting faces substantially normal to said end face and being formed with a plurality of cross bores each communicating at an inner end thereof with a respective one fo said channels, two of said cross bores having outer open ends located at one of said opposite mounting faces and the other of said cross bores having outer open ends located at the other of said mounting faces; external utilization circuits connected to the open ends of said two cross bores; valve means mounted on said other mounting face and communicating with said other cross bores; and a pressure fluid supply line connected to said fifth channel of one of said connecting elements.

Claim 5

A base plate for pressure fluid devices comprising a plurality of connection elements, each of said connection elements comprising a prism-shaped block having a pair of end faces and being formed with five channels extending between said end faces, said channels having on each of said end faces open ends symmetrically arranged with respect to two axes which are normal to each other and the open ends of four of said channels being respectively located at each of said end faces at the corners of a rectangle and the open end of the fifth channel being located at the center of the rectangle, said plurality of connection elements being arranged abutting with said end faces thereof against each other and with said channels respectively aligned with each other, at least some of said prism shaped connecting elements having opposite muounting faces substantially normal to said end face and being formed with a plurality of cross bores each communicating at an inner end thereof with a respective one fo said channels, two of said cross bores having outer open ends located at one of said opposite mounting faces and the other of said cross bores having outer open ends located at the other of said mounting faces; external utilization circuits connected to the open ends of said two cross bores; valve means mounted on said other mounting face and communicating with said other cross bores; and a pressure fluid supply line connected to said fifth channel of one of said connecting elements.

Claim 6

A base plate as defined in claim 3, and including connecting means connecting said blocks to each other for maintaining the end faces of adjacent blocks in abutting relationship.

Claim 7

A base plate as defined in claim 4, wherein each of said blocks is provided with fastening openings arranged symmetrically with respect to said two axes, said connecting means comprising bolts extending through said fastening openings.
