Patent ID: 7150475

Claim:
A modular fluid block system comprising: (a) a pair of fasteners, each having a fastener head; (b) a first block having a first face and an opposite second face, the first block defining: (i) a fluid passage extending through the block; (ii) a pair of fastener passages, each fastener passage having a first end opening at the first face and a second end opening at the second face, the first end opening having a fastener head receiving cavity for receiving the fastener head and the second end opening for receiving the fastener, the pair of fastener passages defining a first diagonal line; (iii) a pair of fastener receiving cavities in the first face defining a second diagonal line; (iv) a pair of fastener head receiving cavities in the second face positioned collinear with the fastener receiving cavities in the first face; and (c) a second block having a third face and an opposite fourth face, the second block defining: (i) a fluid passage extending through the second block; (ii) a pair of fastener passages, each fastener passage having a third end opening at the third face and a fourth end opening at the fourth face, the third end opening having a fastener head receiving cavity, the fastener head receiving cavities of the third face collinear with the fastener head receiving cavities of the second face, and the pair of fastener passages positioned collinear with the second diagonal line; (iii) a pair of fastener cavities in the third face collinear with the first fastener passages; (iv) a pair of fastener head receiving cavities in the fourth face positioned collinear with the first fastener receiving cavities; wherein the first and second blocks are joined between the second and third faces by the fasteners passing through each of the fastener passages in the first block and into the fastener cavities in the third face of the second block.
