IPC: F16K31/02
Filed: 2000-08-01
Abstract: A valve for controlling fluids is proposed that for its actuation cooperates with a piezoelectric actuator (2). To compensate for changes in the length of the piezoelectric actuator (2) in the stroke direction that are caused by temperature changes, a compensation element (7) is provided, which comprises a material that has a coefficient of thermal expansion that is approximately equivalent to that of the piezoelectric actuator (2). The piezoelectric actuator (2) and compensation element (7), upon a certain temperature change, exhibit a comparable change in their length in the stroke direction. As a result, the change in length of the piezoelectric actuator with the temperature is compensated for. The valve is intended for use in fuel injection devices for internal combustion engines.
