Abstract
A fluidic valve for a sample separation apparatus for separating a fluid, wherein the fluidic valve comprises a stack of connected layer structures, a first conduit within the stack, a second conduit within the stack, a movable body within the stack, and an actuator configured for actuating the movable body to selectively bring the movable body into a flow enabling configuration in which flow of fluid between the first conduit and the second conduit is enabled, or into a flow disabling configuration in which flow of fluid between the first conduit and the second conduit is disabled.
Claims12
A fluidic valve for a sample separation apparatus for separating a fluid, the fluidic valve comprising:
- a planar member comprising a stack of layer structures and a non-metallic movable body movable within the stack, wherein the stack comprises a stack of metallic layer structures connected to one another by diffusion bonding;
- a first conduit within the stack;
- a second conduit within the stack;
- an actuator configured for actuating the movable body to selectively bring the movable body into a flow enabling configuration in which flow of fluid between the first conduit and the second conduit is enabled, or into a flow disabling configuration in which flow of fluid between the first conduit and the second conduit is disabled;
- and
- a force transmission structure configured for transmitting an actuation force from the actuator to the movable body, the force transmission structure comprising:
- an elastic membrane as at least one of the layer structures, the elastic membrane arranged between the actuator and the movable body;
- and
- an elastic pad arranged between the actuator and the elastic membrane.
