Abstract: Electromagnetic gas valve with a gas inlet, a gas outlet, and a closure member that is displaceable between an opening position and a closing position. A maximum flow is supplied through the gas outlet with the closure member in the open position and a minimum flow being supplied with the closure member in the closed position. The valve includes a main fluid channel with a closure hole through which the maximum flow is supplied to the gas outlet. The closure member includes a secondary fluid channel calibrated for the minimum flow to pass therethrough, such that the closure member in the closed position covers the closure hole and allows the passage of gas through the secondary fluid channel.

Abstract: Two-way pressure relief valves featuring dual poppets and magnets that allow very rapid flow. Such flow is accomplished by a valve housing enclosing a hollow interior portion containing a stationary member including a magnet and a first pressure-movable poppet disposed in sealing arrangement with the housing and including a second magnet. To provide flow in the other direction, a second moveable poppet disposed coaxially and in sealing arrangement with the first poppet and is coupled to a spring that extends from a first end of the second poppet to a support structure coupled to the second magnet.

Abstract: A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular nature of the apparatus allows for convenient expansion or modification of the manifold assembly to suit any application that comprises a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module in an example can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is readily expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

Abstract: A servo valve is provided with a first elastic portion, a second elastic portion, and a connecting portion. The first elastic portion extends in an X direction inside a valve body and has a first elastic force exerted on a movable element toward an X2 direction. The second elastic portion extends in the X direction inside the valve body and has a second elastic force exerted on the movable element toward an X1 direction. The connecting portion is connected to the first elastic portion and the second elastic portion inside the valve body, and is in abutment against a step portion of the valve body and a spool of the movable element at a neutral position of the movable element.

Abstract: A linear stepper motor with an actuating rod in a housing with a stator, a rotor and a replaceable bearing shield fixed on the stator is provided. The rotor includes a threaded shaft. The bearing shield defines two guide cut-outs. The actuating rod includes a spindle nut portion engaged with the threaded shaft, a replaceable coupling shank for a customer-specific actuating element, and two opposing parallel fork legs which link the spindle nut portion and the coupling shank and which are guided in a rotation-locked manner through the two guide cut-outs.

Abstract: A method for controlling a ventilator includes the steps of providing an inhalation pressure limit, determining when a pressure in a connection to a patient circuit is greater than the inhalation pressure limit, and opening the valve when the pressure is greater than the inhalation pressure limit. An associated computer readable medium for controlling the method is also described.
