Abstract (en)
[origin: US4657480A] A variable control mechanism for a turbine engine, in particular an exhaust gas turbine of a turbocharger, with a ring of guide blades arranged concentrically around a rotor axle and pivoting around pivot axles between end limits. The pivot axles are arranged in the forward areas associated with the inflow edges of the guide blades; one of the end limits being variable by means of an adjusting ring or the like. Clearance and impact losses are incurred depending on the prevailing setting of the guide blades. The invention provides a guide mechanism which can be constructed inexpensively and which reduces clearance and impact losses. The guide blades are arranged such that they can pivot freely within an angular setting range defined by the end limits. In case of a low load the guide blades pivot freely within the predetermined end limits, and with rising loads they abut against the variable end limit.
