Patent ID: 7073825

Claim:
A one-operation piping-installation fluid pressure apparatus comprising: a fluid pressure device including a plurality of solenoid valves to which a plurality of ports is connected, the ports opening on one end face of the fluid pressure device and oriented in a row; a pipe joint assembly including a plurality of pipe joints each having a port connecting portion capable of being connected to a respective port by insertion and a pipe connecting hole to which a respective pipe can be detachably connected, each of the pipe joints being retained by a joint holder having such a length as to be astride all the ports, each of the pipe joints being oriented in a row, and in the same arrangement as the ports of the fluid pressure device with the port connecting portions projecting from a back face of the holder and with the pipe connecting holes exposed on a front face of the holder; and a fixing mechanism for fixing the pipe joint assembly to the fluid pressure device in a connected state, wherein the fluid pressure device is a solenoid valve assembly including a plurality of divided manifold blocks each having a solenoid valve provided on an upper face of the manifold block and two side blocks disposed on opposite sides of a row of the manifold blocks, at least one of the two side blocks also functioning as an air supply/exhaust block, each of the manifold blocks has two of the ports including upper and lower output ports communicating with the mounted solenoid valve on the upper face of the manifold block, the at least one air supply/exhaust block has an air supply port and an exhaust port communicating with each of the manifold blocks, said air supply/exhaust ports form parallel upper and lower ports in the solenoid valve assembly, and the pipe joint assembly includes parallel rows of upper and lower pipe joints constituted of the plurality of pipe joints.
