Abstract: A two-component rotary valve for controlling the fluid flow through a fluid conduit, the rotary valve being injection-moulded in two steps with no need for assembly after the injection moulding procedure. The rotary valve comprises a valve house with a plug inside it, and the rotary valve has sealing means in the form of local variations in the radius of the plug and house along their lengths. Thereby, a rotary valve is obtained which does not require a viscous sealant, such as silicone, to eliminate the risk of leakage, when the valve is open.

Abstract: A core drilling system is disclosed herein in which a torque tube has a groove or keyway which receives a rotating wheel or key to prevent a transmission box and motor from rotating during drilling operation. As such, the operator does not need to hold a stabilizing arm to resist counter rotational forces during the drilling process. The operator may focus on the hole to be cut in a substrate. Additionally, a torque tube stabilizing leg assembly may be secured to the free distal end portion of the torque tube.
