Patent number: 11898583Abstract: In a cushion mechanism of a gas cylinder, when the pressure of a gas in a first pressure chamber is less than or equal to a prescribed pressure, a valve body cuts off communication between the upstream side and downstream side of a discharge flow passage by mean of the biasing force of a spring member. In addition, when the pressure of the gas exceeds the prescribed pressure, the valve body is displaced to the downstream side of the discharge flow passage against the biasing force, thereby enabling communication between the upstream side and the downstream side of the discharge flow passage.Type: GrantFiled: July 20, 2020Date of Patent: February 13, 2024Assignee: SMC CORPORATIONInventors: Seiichi Nagura, Naoki Shinjo, Kazutaka Someya, Akihiro Kazama, Yusuke Mori

Patent number: 11143175Abstract: A pressure booster constituting a cylinder apparatus is provided with a first piston and a second piston that are coupled to each other by a rod. A connection member provided to the second piston is configured so as to be displaceable from a connection position to a blocking position as a result of the connection member making contact with a cylinder body when the second piston is displaced in a direction where a boosting chamber contracts, and so as to be displaceable from the blocking position to the connection position as a result of the connection member making contact with the cylinder body when the second piston is displaced in a direction where the boosting chamber expands.Type: GrantFiled: March 5, 2018Date of Patent: October 12, 2021Assignee: SMC CORPORATIONInventors: Hiroyuki Asahara, Kazutaka Someya

Publication number: 20210293258Abstract: A first position detection sensor and a second position detection sensor of a pressure booster detect the position of a first piston or a second piston. A fluid supply mechanism supplies a fluid to a first pressure-boosting chamber and/or a second pressure-boosting chamber. On the basis of the detection results of the first position detection sensor and the second position detection sensor, the fluid supply mechanism switches between performing an operation for supplying fluid to a first drive chamber and discharging fluid from a second drive chamber, and performing an operation for discharging fluid from the first drive chamber and supplying fluid to the second drive chamber.Type: ApplicationFiled: August 17, 2017Publication date: September 23, 2021Applicant: SMC CORPORATIONInventors: Hiroyuki ASAHARA, Kengo MONDEN, Naoki SHINJO, Seiichi NAGURA, Kazutaka SOMEYA

Patent number: 11028860Abstract: A pressure booster having arranged therein drive cylinders on both sides of a boosting cylinder is provided with a pair of pilot valves that are actuated when pistons of the drive cylinders abut against the moving ends thereof. A pair of actuation valves switch the supply state of a pressure fluid to pressure chambers of the drive cylinders. When the pilot valves are actuated, the pressure fluid passes through the pilot valves and is supplied to the pair of actuation valves, and the supply state of the pressure fluid is switched.Type: GrantFiled: May 11, 2018Date of Patent: June 8, 2021Assignee: SMC CORPORATIONInventors: Yoshiyuki Takada, Kengo Monden, Kazutaka Someya

Publication number: 20210108657Abstract: A fluid circuit for air cylinders is provided with a switching valve, an air supply source, an exhaust port and a check valve. When the switching valve is in a first position, one cylinder chamber is connected with the air supply source and the other cylinder chamber is connected with the exhaust port. When the switching valve is in a second position, the one cylinder chamber is connected with the other cylinder chamber via the check valve, and the one cylinder chamber is connected with the exhaust port. The acoustic velocity conductance of a pipe connecting the switching valve and a cylinder port part of the one cylinder chamber is lower than the acoustic velocity conductance of the switching valve and the cylinder port part of the one cylinder chamber.Type: ApplicationFiled: May 18, 2018Publication date: April 15, 2021Applicant: SMC CORPORATIONInventors: Yoshiyuki TAKADA, Youji TAKAKUWA, Hiroyuki ASAHARA, Kengo MONDEN, Kazutaka SOMEYA

Publication number: 20200232449Abstract: A boosting device is provided with a drive unit which is driven under the action of energization, and a boosting mechanism which is connected to the drive unit and which boosts and outputs a pressurized fluid. The boosting mechanism comprises a rotating body which is connected to a drive shaft of a drive source and includes a slope portion, and four pistons opposing the rotating body and disposed moveably in an axial direction. The pistons are sequentially and continuously pushed in the axial direction by means of the slope portion of the rotating body, whereby the pressurized fluid is compressed and boosted in a boosting chamber.
