Abstract
An angle measuring instrument that includes an outer component having a front face and an inner component, wherein the outer component is rotated relative to the inner component about an axis of rotation and the outer component lies further from the axis of rotation than the inner component along a radial direction with respect to the axis of rotation. A seal formed between the outer component and the inner component and wherein the front face includes a conduit, which leads radially outward and is located lower with respect to the front face.
