Title: Lothar Koelsch: Innovator in Valve Technology and Optical Systems
Introduction
Lothar Koelsch is a notable inventor based in Wilnsdorf, Germany. He has made significant contributions to the fields of valve technology and optical systems, holding a total of 3 patents. His innovative designs reflect a deep understanding of engineering principles and practical applications.
Latest Patents
One of Koelsch's latest patents is a switchable flap valve. This valve features at least one valve plate that pivots about a longitudinal axis within a housing part. The design includes a strip element aligned parallel to the valve plate's longitudinal axis, which forms a hollow channel with an adjacent housing wall. This mechanism allows for the valve plate to pivot to an open position when pressure is introduced into the hollow channel, demonstrating a clever integration of mechanical and fluid dynamics.
Another significant patent is his telephoto camera lens. This lens is constructed from two different lens systems: a front group and a focusing group. The front groups contain fixedly arranged lens elements, while the focusing groups have mutually displaceable lens elements. This modular design allows for the creation of telephoto lenses with varying focal lengths, enhancing imaging performance while reducing production costs.
