Company patents

ECO Holding 1 GmbH

ECO Holding 1 GmbH's patent strategy appears to be undergoing a significant shift, moving away from its historical dominance in "Valves" (79.1% of its portfolio) which saw a 25.0% decline in 2025 and a sharp 66.7% decline so far in 2026. Surprisingly, despite a strong 100.0% YoY growth in "Batteries & Fuel Cells" in 2024, this category has also seen a complete halt in patenting activity so far in 2026, indicating a potential re-evaluation of its energy storage focus.

Electromagnetic proportional valve and system having a proportional valve

Filed:2019-12-17Pub:2025-07-15
Applicant:ECO Holding 1 GmbH

The invention relates to an electromagnetic proportional valve, preferably for refrigerant, which has the following: an armature of an electromagnet which is arranged so as to be able to be moved axially between an idle position, an activation position and working positions and on which an activation element is arranged; a piston which is constructed as a hollow piston and which has at a first axial end region a first opening toward a supply of the expansion valve and at a second axial end region a second opening toward a pressure compensation space; and a blocking member which is constructed to close the second opening, wherein the piston is arranged so as to be able to be axially displaced and wherein the piston is constructed to block a fluid passage as a blocking element of a main valve device, wherein the fluid passage of the main valve device is blocked in the idle position of the armature, wherein the activation element is constructed to act in the activation position of the armature on the blocking member in such a manner that it releases the second opening at least in regions, and wherein the fluid passage of the main valve device is open in the working positions of the armature. The invention further relates to a system having such a proportional valve.
