Manifold air pressure feeder and manifold block for use in manifold air pressure feeder

Abstract

[Object] To provide a manifold air pressure feeder and a manifold block for use in the manifold air pressure feeder that yield reductions in the piping installation work and other workloads associated with a pressure sensor configured to determine the pressure of compressed air in the manifold block and save installation space. [Solution] An air pressure feederincludes a manifold blockand a switching valve block. A first port group and a first flow path group are located in the manifold block. The switching valve blockincludes a spoolto perform switching between communication states of a plurality of ports in a second port group. These blocks are linked directly or indirectly to each other via an ejector including a connection flow path group that forms a connection between each port in one of the port groups and the corresponding port in the other ort group. The manifold blockincludes a pressure sensor assembly, which measure air pressure in a second feed flow pathand includes a sensor partand a sensor substrate part. The manifold block includes a sensor installation cavity, which communicates with the second feed flow path. The sensor part is inserted and fixed in the sensor installation cavity.
