Abstract

A compact flow control valve capable of providing long service life in a very hostile environment. The valve is a mono or dual coaxial slider valve capable of controlling two different functions sequentially, at least one of the functions being controlled progressively. The flow control valve controls the fluid connection between two volutes (6, 7) of a turbine housing (2) of a turbocharger as well as the fluid connection between the two volutes (6, 7) of the turbine housing (2) of the turbocharger and a waste gate port (9).
