Patent ID: 8347921

Claim:
A parallel type valve assembly having two connected valve units each formed by directly abutting respective joint surfaces of side surfaces of plural electromagnetic valves and serially connecting the electromagnetic valves in a row, the two connected valve units arranged in parallel to each other between two end blocks, the two end blocks being tightened with plural connecting bolts disposed therebetween to directly clamp and fix the two connected valve units from both sides in a serial connection direction of the electromagnetic valves, wherein: the electromagnetic valve includes a valve housing having a first joint surface and a second joint surface on both side surfaces for a serial connection, an air inlet hole and a discharge hole which penetrate the valve housing in the serial connection direction, and a valve connector for electric coupling, when the plural electromagnetic valves are serially connected, the air inlet holes and the discharge holes of the respective electromagnetic valves are serially connected to form a collective air inlet flow path and a collective discharge flow path, and the valve connectors of the adjacent electromagnetic valves are electrically coupled with each other; the two end blocks include an inner end surface having a size required for straddling the joint surfaces of the two electromagnetic valves positioned so as to face each other at each end of the two connected valve units, an outer end surface positioned opposite the inner end surface, a front end surface and a rear end surface, and an upper surface and a lower surface, the inner end surface of respective end blocks straddles and abuts the joint surfaces of the two electromagnetic valves at the end of the two connected valve units, a first end block among the two end blocks includes a power supply connector for supplying power to the electromagnetic valve, a connector substrate for retaining relay connectors, and two relay connectors disposed alongside on the connector substrate, electrically coupled with the power supply connector, and individually electrically coupled with the two connected valve units, and second end block as at least the other one of the two end blocks includes air inlet ports and discharge ports communicated with the collective air inlet flow paths and the collective discharge flow paths of the connected valve units.
