Patent number: 11280409Abstract: A hydraulic fluid cylinder is equipped with a cylinder tube, a piston unit, and a piston rod. The piston unit has a gasket and a piston body comprising a plurality of members and provided with a gasket-mounting groove. The piston body has a first piston member which projects to the outside from the piston rod, and also has a second piston member positioned so as to be adjacent to the first piston member. The gasket-mounting groove is formed from a combination of at least two members.Type: GrantFiled: June 27, 2017Date of Patent: March 22, 2022Assignee: SMC CORPORATIONInventor: Tsukasa Odaka

Patent number: 11143214Abstract: A rod assembly for a fluid pressure cylinder has a rod member and a packing that is mounted on an outer circumferential part of the rod member and slides along a slide hole. Assembly is simple because a conventional hard piston is not used. The assembly can be carried out simply by hand without the use of a dedicated tool. Thus, the rod assembly simplifies assembly work.Type: GrantFiled: November 13, 2017Date of Patent: October 12, 2021Assignee: SMC CORPORATIONInventor: Tsukasa Odaka

Publication number: 20210262572Abstract: A seal structure includes a mounting groove disposed in a first member and a packing unit housed in the mounting groove. The packing unit includes an inner circumferential mounting section and an outer circumferential sliding section. Both side surfaces of the packing unit are conical surfaces which are inclined such that their diameters gradually increase in a direction from the mounting section toward the sliding section and which are inclined in mutually opposite directions. The thickness of the packing unit increases in a gradual manner in the direction from the mounting section toward the sliding section, the thickness in the mounting section is the smallest, and the thickness in the sliding section is the largest.Type: ApplicationFiled: June 6, 2019Publication date: August 26, 2021Applicant: SMC CORPORATIONInventors: Masayuki KUDO, Kenichi TAKEDA, Masahiko KAWAKAMI, Ken TAMURA, Tsukasa ODAKA

Patent number: 11079017Abstract: A hydraulic cylinder (10) comprises a cylinder tube (12) having a circular slide hole (13), a piston unit (18), and a piston rod (20). The piston unit (18) has a circular piston body (40), packing (42) that is installed on the outer circumferential portion of the piston body (40), a movable member (44) that is mounted to the outer circumferential portion of the piston body (40) so as to be able to rotate relative to the piston body (40), and a magnet (46) that is held by a magnet holding unit (58) of the movable member (44). Relative rotation of the movable member (44) with respect to the cylinder tube (12) is regulated.Type: GrantFiled: February 26, 2018Date of Patent: August 3, 2021Assignee: SMC CORPORATIONInventor: Tsukasa Odaka

Publication number: 20210003152Abstract: A packing has an outer circumferential surface and includes a pair of sealing parts located at opposite ends of the packing in a direction along an axis. A piston has a sliding face having a first recess groove. When in the first recess groove, the packing has an outside diameter smaller than the diameter of a slide-receiving face of a cylinder hole. The piston divides the cylinder hole into a pair of chambers. While a compressed fluid is supplied to either one of the chambers, a side edge of the packing adjacent to the chamber at a high pressure is stretched in a radial direction by elastic deformation due to the pressure of the compressed fluid, thus causing a sealing part adjacent to the chamber at the high pressure to reduce a gap formed with the slide-receiving face of the cylinder hole or come into contact with the slide-receiving face.Type: ApplicationFiled: February 20, 2019Publication date: January 7, 2021Applicant: SMC CORPORATIONInventors: Masayuki KUDO, Kenichi TAKEDA, Masahiko KAWAKAMI, Ken TAMURA, Tsukasa ODAKA

Patent number: 10851813Abstract: A hydraulic fluid cylinder is equipped with a cylinder tube, a piston unit, and a piston rod. The piston unit has a piston body comprising a plurality of members and provided with a gasket-mounting groove. The piston body has a first piston member and a second piston member which are layered in the axial direction. The gasket-mounting groove is formed from a combination of at least two members. A thin section exhibiting depth in the axial direction is provided in the first piston member and/or the second piston member.Type: GrantFiled: June 27, 2017Date of Patent: December 1, 2020Assignee: SMC CORPORATIONInventor: Tsukasa Odaka
