    Abstract: A position detection assembly for detecting a spatial position of a moveable element. The assembly includes a colour sensor and one or more colour indicators provided on a surface of the moveable element. The colour sensor is spaced from the surface of the moveable element and arranged to emit light onto the surface and detect light reflected from the surface and to determine the position of the element based on the reflected light.

    Abstract: A valve assembly includes a movable valve element arranged to move relative to a valve housing between an open and a closed position. The valve housing includes a drainage body provided with drainage holes arranged to allow fluid to drain from the valve assembly from gaps between the movable valve element and the housing via the drainage holes.

    Abstract: A fluid level sensor assembly includes a first pipe component defining a flow path for the fluid and configured to be attached to a valve to control flow of the fluid from the first pipe component, and a fluid level sensor arranged in or on the first pipe component to detect a level of fluid in the first pipe component and to generate a command signal for operation of the valve according to the level detected. The assembly also includes an insert fitted to an end of the first pipe component and extending axially from the end to be fitted to an inlet of the valve, in use, wherein the insert is configured to secure the first pipe component against rotation relative to the valve inlet when the insert is fitted to the inlet.

    Abstract: A closure assembly for a fluid port having a fluid flow channel defined along an axis, the channel ending in a port opening. The assembly includes: a closure cap extending in a first plane arranged to seat across, and close the port opening, in use, in a closed state, a guide arm extending from the cap in a second plane substantially perpendicular to the first plane; a lifting guide to accommodate and retain the guide arm for movement of the guide arm in the second plane as the cap moves axially away from the opening; and a pivot mechanism between the guide arm and the lifting guide about which the cap is able to pivot relative to the lifting guide to an open position.

    Abstract: A connector assembly includes a first connector part and a second connector part, each connector part defining a fluid flow passage therethrough configured to together define a fluid flow conduit when the first and second parts are connected together. The connector assembly also includes an extension part mounted around one of the first and the second connector parts. The extension part is arranged to move relative to the connector part around which it is mounted to extend across an interface area between the first connector part and the second connector part and to bridge the first and second connector parts when the first and second connector parts are brought to meet each other to define the fluid conduit.

    Abstract: A vane for use in a rotary vane pump. The vane has a length L extending between a first edge of the vane and a second edge of the vane and a width W extending perpendicular to said length, the width extending between a third edge of said vane and a fourth edge of the vane, and further comprising a channel extending through said vane and provided at a position along said length L of said vane. The channel maybe positioned away from said first and second edges such that said vane has a constant length L along its width. The width of the channel may vary in shape between first and second points along the length of the vane. The channel may have a triangular shape, a rectangular shape or a circular shape. A method for detecting the decrease in length of the vane is also described.

    Abstract: A multi-way valve assembly includes a valve housing having a plurality of fluid ports, a first valve member having one or more first flow channels defined therethrough and a first shaft, rotation of which causes rotation of the first valve member relative to the housing, the first valve member defining a cavity, and a second valve member arranged within the cavity of the first valve member and having one or more second flow channels defined therethrough and a second shaft. Rotation of the second shaft causes rotation of the second valve member relative to the housing. The assembly also includes a locking mechanism configured to, in a locked position, cause the second valve member to rotate with the first valve member relative to the housing and, in an unlocked position, to permit the second valve member to rotate relative to the first valve member and the housing.
