Patent number: 11680650Abstract: A four-position switching valve includes first and second pistons for driving a spool in a valve body, and a spool moving mechanism part that moves the spool to first and second intermediate switching positions between one-end side and the other-end-side switching positions. The spool moving mechanism part includes a compression spring that moves the spool back in the opposite direction by moving to the switching position on one end side and the other end side of the spool. The compression spring moves the spool to the first intermediate switching position when the spool moves to one-end-side switching position and the pressure on the second piston is released, and moves the spool to the second intermediate switching position when the spool moves to the other-end-side switching position and the pressure on the first piston is released.Type: GrantFiled: March 23, 2022Date of Patent: June 20, 2023Assignee: SMC CORPORATIONInventor: Kenichi Matsumura

Publication number: 20220403856Abstract: An ejector includes an ejector body having an internal passage and a negative-pressure generating mechanism including a nozzle unit and a diffuser unit that generates a negative pressure by using compressed air ejected by the nozzle unit. The ejector body has a first attachment surface to which a valve body of a switching valve is attached and a second attachment surface to which a base body of the manifold base is attached. The first attachment surface has a first inflow port for supplying compressed air to the negative-pressure generating mechanism by being connected to a first output port of the switching valve, and this port communicates with the nozzle unit. The second attachment surface has a negative-pressure supply port for outputting a negative pressure to the outside by being connected to a negative-pressure inflow port of the manifold base, and this port communicates with the diffuser unit.Type: ApplicationFiled: May 23, 2022Publication date: December 22, 2022Applicant: SMC CORPORATIONInventor: Kenichi MATSUMURA

Publication number: 20210324961Abstract: Enlarged holes are formed at respective end portions of a valve hole housing a spool by forming an upper recessed groove and a lower recessed groove at each end portion. The respective lower recessed grooves are in communication with discharge ports. The spool includes discharge lands and discharge packing portions, which open and close discharge passages connecting an output port and the discharge ports. When the discharge land and the discharge packing portion open the discharge passage by displacing of the spool, the discharge passage and the discharge port are in communication with each other through the enlarged hole by positioning the discharge land and the discharge packing portion inside the enlarged hole.Type: ApplicationFiled: July 11, 2019Publication date: October 21, 2021Applicant: SMC CORPORATIONInventors: Yoshiyuki TAKADA, Shinichi YOSHIMURA, Masaru YOSHIDA, Kenichi MATSUMURA, Yoichi MORODOMI
