    Abstract: A microvalve device for controlling fluid flow in a fluid circuit (10). The microvalve device comprises a body (12) having a cavity formed therein. The body further has first (20) and second (22) pilot ports placed in fluid communication with the cavity. The body also has first (28) and second (30) primary ports placed in fluid communication with the cavity. Each port is adapted for connection with a designated fluid source. A pilot valve (36) supported by the body is movably disposed in the cavity for opening and closing the first and second pilot ports. An actuator (38) is operably coupled to the pilot valve for moving the pilot valve. A microvalve (40) is positioned by the fluid controlled by the pilot valve. The microvalve is a slider valve having a first end (40a) and a second end (40b). The slider valve is movably disposed in the cavity for movement between a first position and a second position. The first end of the slider valve is in fluid communication with the first and second pilot ports when the first and second pilot ports are open. The second end of the slider valve is in constant fluid communication with the first primary port. When moving between the first and second positions, the slider valve at least partially blocks and unblocks the second primary port for the purpose of variably restricting fluid flow between the primary ports.

    Abstract: The proposal is for a multilayer microvalve for switching or controlling fluid flows having an inlet and a shut-off component. The inlet is formed as at least one aperture in a first layer. The shut-off component takes the form of a second layer applied to the first. This second layer (15) has at least one further aperture in the region of the shut-off component. The shut-off component can be moved substantially parallel to the first (25) and second (15) layers, especially by electrical actuating means, so that, in at least a first position of the shut-off component, at least one inlet aperture together with at least one further aperture in the second layer (15) forms at least one through-flow aperture. The cross-section of the at least one through-flow aperture can be changed by actuating the shut-off component.

    Abstract: An assay apparatus for determining properties of a sample. The apparatus has first and second chambers for receiving a sample. The first and second chambers are linked by a conduit along which at least part of the sample may travel so that the sample can move from the first chamber to the second chamber in series. The apparatus also has a slot extending from the conduit and a valve body comprising magnetic or magnetically susceptible material which is housed at least substantially within the slot. The valve body is movable between a first position in which the valve body is arranged at least substantially outside the conduit and a second position in which the valve body extends across the conduit thereby restricting a sample from travelling along the conduit from the first chamber to the second chamber. The valve body is slidably movable between the two positions by an external magnetic field.

    Abstract: A microfluidic control valve (100) comprising a dielectric structure (105) defining at least one cavity (260) therein. An electroactive material (305), such as an electroactive polymer, is disposed in a portion of the cavity. The electroactive material is operable between a first state in which a dimension of the electroactive material has a first value and a second state in which the dimension has a second value. Two conductors (240, 250) can be included for applying a voltage potential across the electroactive material to change the electroactive material between the first state and the second state. A first fluidic port (310) can be located proximate to the electroactive material such that a fluid flows through the first fluidic port when the electroactive material is in the first state, and the electroactive material at least partially blocks the first fluidic port when the electroactive material is in the second state.
