Abstract
A combination high pressure accumulator/bypass valve assembly suitable for vehicle control systems such as anti-lock braking systems and traction control systems employs a stationary seal and a reduced part count favoring economy of manufacture and assembly, and eliminates the dynamic seal/light alloy interface, significantly reducing the potential for failure due to pump body/seal abrasion. A caged spring assembly further encourages ease of assembly.
