With a total of 5 patents to his name, Breitbach's work exemplifies the intersection of creativity and technical expertise.

Latest Patents

One of Breitbach's latest inventions is an actuator that incorporates a piezoelectric stack within a housing designed to apply a compressive load to the stack. This actuator features a cylindrical tube that is closed at one end, effectively sealing the stack against fluid pressure. The housing is shorter than the length of the piezoelectric stack and includes resilient means to induce elastic strain in the stack. These resilient means may consist of slots extending around the circumference of the housing or a corrugated region that forms a tension spring at the lower end, drawing the stack into compression. The stack itself comprises multiple layers of piezoelectric or piezoceramic material interspersed with layers of electrically conductive material, along with connecting means for electrical power.

Another significant patent is the needle lift damper device for fuel injection, which aims to achieve a consistently stable needle lift damping effect in injectors. This invention includes a damper member that is slidably mounted to the needle valve, a damping chamber formed between the damper member and the needle valve, and a leak passage for extracting fuel from the damping chamber. The needle valve serves as a guide for the damper member, preventing vibrations and ensuring a stable damping effect.
