Patent ID: 7588434

Claim:
A fluid distributor and operational drive of a molding system, comprising: a block forming a manifold for distributing a fluid, the block including: a fluid distribution circuit having at least one fluid inlet port and at least one fluid outlet port; a first interface being disposed on a side of the block, the first interface providing a mount and connection to a stationary device; a second interface being disposed on an opposite side of the block, the second interface being configured to provide a mount and connection to an electric motor; a cylinder bore being formed in the block, the cylinder bore being interconnected to the fluid distribution circuit, one end of the cylinder bore being open to a surface of the block that includes the first interface; a shaft member being translatable member, intermediate of the ends of the shaft member including a piston section being cooperative with the cylinder bore, the cylinder bore being of a diameter to receive the piston section for reciprocation by the fluid of the fluid distribution circuit, and seals being intermediate the piston section and the cylinder bore, a pass thru bore being formed in an opposite end of the cylinder bore for receiving and passing a portion of the shaft member, one end of the shaft member including an interface member, the interface member including a coupler being configured to engage with a movable machine member, the other end of the shaft member including an operational member, an interface being disposed on a section of the operational member; a surface of the block with the first interface and an inside diameter of the cylinder bore being cooperative to receive an interface member end cap, and a surface of the interface member end cap providing a stop for the piston section of the shaft member; and a drive cap being disposed on a surface of the second interface of the block, the drive cap being rotatable by the electric motor, and rotation of the drive cap rotates the shaft member through the interface while permitting translational movement of the shaft member.
