Abstract
A valve comprising a first pan (10′) defining a first array of apertures (20′) and a second part (50) defining a second array of apertures (60′), the first pan (10′) being moveable relative to the second part (50) between a first configuration in which passage of a fluid through the valve is substantially prevented and a second configuration in which passage of fluid is allowed. In one embodiment, the first pan (10′) comprises a flexible plate-like member configured to engage a sealing face of the second part (50) when in the second configuration and lock in the second configuration in response to a pressure differential across the valve. The plate-like member is sufficiently flexible to conform to a profile of the sealing face in response to a pressure differential across the valve.
Claims13
A valve comprising a first part defining a first array of apertures and a second part defining a second array of apertures, the first part comprising a flexible plate-like member and being moveable laterally relative to the second part between a closed configuration in which the first and second arrays of apertures are not registered and passage of a fluid through the valve is substantially prevented and an open configuration in which the first and second arrays of apertures are registered and passage of fluid is allowed;
- wherein the first part is constrained to move substantially parallel to a surface defined by the sealing face of the second part by a retaining plate, and
- wherein the valve is provided on a piston such that the second part comprises a piston face.
A valve comprising a first part defining a first array of apertures and a second part defining a second array of apertures, the first part comprising a flexible-like member and being moveable laterally relative to the second part between a closed configuration in which the first and second arrays of apertures are not registered and passage of a fluid through the valve is substantially prevented and an open configuration in which the first and second arrays of apertures are registered and passage of fluid is allowed;
- wherein the first part comprises more than one moveable valve plate, which are configured in one layer or in multiple layers, and
- wherein the valve is provided on a piston such that the second part comprises a piston face.
