Introduction

Jyrki Kajaste, an accomplished inventor based in Vihti, Finland, has made significant contributions to the field of hydraulic engineering. With two patents to his name, Kajaste has developed innovative technologies that enhance the efficiency and effectiveness of hydraulic systems.

Latest Patents

Kajaste's latest patents include the "Plunger Pressure Accumulator" and the "Adaptive Hydraulic Pressure Generator." The Plunger Pressure Accumulator features a shell with a plunger that moves relative to it, creating at least two subspaces—one supplied with hydraulic fluid and the other filled with pressurized gas. This design includes a slide element that supports the plunger's movement while maintaining a distance from the internal surfaces of the subspaces. Moreover, the accumulator is equipped with a stationary regenerator, enhancing its functionality.

The Adaptive Hydraulic Pressure Generator is designed for systems where mechanical force varies significantly, such as wave energy systems. It comprises two fluid chambers allowing a piston surface to reciprocate. By utilizing a control system that connects these chambers and adjusts the effective area of the piston according to the driving force, this generator produces pressure in the supplied fluid that exceeds the necessary threshold.
