Title: Rolf Kunzmann: Innovator in Valve Technology

Introduction

Rolf Kunzmann is a notable inventor based in Gernsbach, Germany. He has made significant contributions to the field of valve technology, holding three patents that showcase his innovative spirit and technical expertise. His work primarily focuses on the development of advanced valve systems that enhance fluid control and efficiency.

Latest Patents

Kunzmann's latest patents include an innovative expansion valve design. This valve comprises a first port, a second port, and a fluid path extending between them. A valve member is situated in the fluid path, which can be selectively moved between a closed position, blocking the fluid path, and an open position. The design features an armature coupled to the valve member and a solenoid that forms a linear actuator with the armature. Notably, a portion of the armature's surface directly faces the solenoid, enhancing its functionality.

Another significant patent involves a method for operating a valve, along with an associated electronic control unit and valve drive. This method determines a nonlinear characteristic curve function that indicates the required relationship between a valve opening position and the flow of fluid. The function is stored in an electronic control unit (ECU) and is used to set the valve opening position with a control signal indicating a target flow. The function can be calculated automatically using a parameter value, an analytic function, or by interpolation with specified supporting values provided by a user.
