Abstract
A machined spring for injector applications includes opposed first and second spring bases separated apart along a longitudinal axis. A spring body connects the first and second spring bases. The spring body includes a generally annular wall with a plurality of spring channels defined therethrough, such as machined channels. Exemplary applications for such machined springs include liquid strainers, valve components, and structural components for accommodating thermal expansion in injectors.
