摘要： An actuator includes a first enclosure, a dielectric fluid in the first enclosure, and a second enclosure in fluid communication with the first enclosure. An elastic membrane defines at least a portion of the second enclosure. A first electrical conductor is positioned along a first side of the first enclosure. A second electrical conductor is positioned along a second side of the first enclosure opposite the first side. The second conductor is spaced apart from the first conductor. The conductors are connected to a power source. Application of electrical energy to the first and second conductors produces an attractive force between the conductors. Motion of the conductors toward each other pressurizes the dielectric fluid so as to force the dielectric fluid to flow from the first enclosure into the second enclosure. The flow of the dielectric fluid exerts a force on the elastic membrane which expands the elastic membrane.

摘要： A system that utilizes a very thin arrangement of transparent sub panels containing embedded very small distributed electromagnet wires to control the distribution of very fine magneto-rheological fluid particles suspended in a very thin panel sandwiched between the electromagnet wire panels. The current applied to specific electromagnets may be used to control the amount of electromagnetic energy, such as visible light, that can be transmitted through the panel system. The system may also be used to increase or decrease the rigidity of the multi-panel structure as a function of current applied to the electromagnets.

摘要： A sanitary valve system (10) comprising an actuator arrangement (20) in an actuator housing (32) comprising a first piston chamber (30I) with a first piston (32I) separating the first piston chamber in a first upper cavity (34IU) and a first lower cavity (34IL) and having a first piston shaft (36I) configured to operate outside of the actuator housing. The valve system is configured to operate in multiple states. The operation of each state and transitions amongst states including identical states are controlled by regulating the liquid pressure or flow in each respective first and second upper and lower cavities. The regulation of liquid may be via a common distribution plate arrangement (90). The distribution arrangement may be with least one common distribution plate (92) with a set of canals (94) configured to connect at least one set of upper and lower regulation lines (82IU, 82IL,82IIU, 82IIL) with the respective first and second upper and communication lines (50IU, 50IL, 50IIU, 50I IL). A sanitary valve kit and a method of retrofitting an existing valve arrangement are also disclosed.

摘要： An actuator, such as a pressure actuator or a vacuum actuator, has a housing and a plunger that is guided through the housing. A diaphragm is connected to the housing and to the plunger and forms a gas-tight pressure chamber with the housing. A pressure medium connector is provided on the housing and communicates with the pressure chamber to pressurize the pressure chamber. A braking element is provided on the plunger and enables a braking force can be exerted on the plunger.

摘要： A method of compressing a gas includes pumping, using a pump, at least a portion of a liquid contained in a first chamber to a second chamber containing a gas at a first pressure such that the portion of the liquid pumped into the second chamber compresses the gas in the second chamber to a second pressure greater than the first pressure, wherein the portion of the liquid pumped into the second chamber is admitted into the second chamber so that the admitted liquid flows along an internal surface of the second chamber.

摘要： A method for adapting stiffness in a variable stiffness actuator includes a member configured to transmit motion that is connected to a fluidic circuit, into which a control fluid circulates. The fluidic circuit includes a supply and distribution unit of the control fluid having a reservoir of the control fluid and a pumping unit. The supply and distribution unit includes two distribution lines of the control fluid, which are fluidly connected to the actuator such that an increase and/or decrease in the pressure of the control fluid activates the member that transmits motion. The stiffness of the actuator is adapted by adapting the pressure of the control fluid into the two distribution lines. The present invention includes also a variable stiffness actuator utilizing the above method for adapting stiffness.
