Latest Patents
Among his latest inventions is a gate valve designed to enhance sealing efficiency. This gate valve features a cylindrical angle-transported disc gate that can pivot into a channel-closing position. In this position, it engages with a packing ring located in a radial packing groove, ensuring a tight seal. The design allows the outer diameter of the packing ring to be smaller than that of the packing groove, which facilitates a secure sealing engagement when the gate is closed.
Another significant invention by Nelimarkka is a two-way linear actuator. This actuator converts the linear movement of a piston into the rotational movement of a shaft. It consists of two cylinders, a piston that moves within them, and a torque shaft positioned at a right angle to the piston movement. The actuator is designed with a machine element that connects the torque shaft to the piston, ensuring efficient operation while being sealed from the interior of the cylinders.
