Abstract:
1. A modular fluid block system comprising: a first block having a first face, a second face and at least two opposed fastener passages, wherein each of the opposed-fastener passages has (i) a first end opening to the first face, (ii) a second end opening to the second face, and (iii) a head receiving portion at the first end opening, and wherein the first block further includes a fluid passage disposed between the first and second faces; a second block having a third face, a fourth face and at least two of opposed fastener passages, wherein each of the opposed fastener passages has (i) a third end opening to the third face, and (ii) a fourth end opening to the fourth face, and wherein the second block further includes (i) at least two fastener receiving cavities in the third face, and (ii) a fluid passage from the third and fourth faces, wherein the first and second blocks are joined between the second and third faces by no more than two fasteners passing through the at least two opposed fastener passages in the first block, wherein each of the at least two fasteners is removably secured into one of the at least two fastener receiving cavities, wherein each of the two fasteners includes a head portion, wherein when each of the two fasteners is secured into its corresponding fastener receiving cavity at least a portion of each of the head portions is received into a corresponding head receiving portion, wherein each of the head receiving portions is sufficiently small in diameter such that the head portion cannot shift laterally by more than a predetermined amount, and wherein the predetermined amount is less than the amount of shift that results in a leak in the interface between the first and second blocks.
