Abstract
A hydrodynamic torque converter has a converter circuit having at least a pump wheel and a turbine wheel, wherein each of these wheels has a blade amazement to form flow chambers, each of these blades being provided at its free end with a stiffener acting as part of a toroid. A choke element is provided which can move by a predetermined depth into the associated blade arrangement and serves to regulate the through-flow cross section for the hydraulic fluid of the converter circuit which is supplied in that it is connected via a line system to a supply arrangement. The choke element is arranged in the toroid and is provided with at least one choke projection which penetrates into a corresponding cutout in the toroid and can move into at least one associated flow chamber.

A hydrodynamic torque converter, comprising:
- a pump wheel rotatably mounted about an axis of rotation;
- a turbine wheel rotatably mounted for rotating relative to said pump wheel about said axis of rotation;
- each said pump wheel and said turbine wheel comprising a blade arrangement forming flow chambers, said blade arrangements comprising stiffeners defining part of a toroid between said pump wheel and said turbine wheel;
- said toroid comprising a cutout adjacent a flow chamber of one of said blade arrangements;
- a converter circuit for conducting hydraulic fluid through said flow chambers of said blade arrangements and connected to a hydraulic fluid supply arrangement via a line system;
- and
- a choke element having a choke projection and movably mounted in said toroid so that said choke projection is operatively movable through said cutout and insertable into said flow chamber of said one of said blade arrangements for regulating a through-flow cross section of said flow chamber of said one of said blade arrangements, wherein said choke element comprises a plurality of choke projections arranged at predetermined circumferential intervals, each one of said plural choke projections being insertable into an associated flow chamber of said one of said blade arrangements.
A hydrodynamic torque converter, comprising:
- a pump wheel rotatably mounted about an axis of rotation;
- a turbine wheel rotatably mounted for rotating relative to said pump wheel about said axis of rotation;
- each said pump wheel and said turbine wheel comprising a blade arrangement forming flow chambers, said blade arrangements comprising stiffeners defining part of a toroid between said pump wheel and said turbine wheel;
- said toroid comprising a cutout adjacent a flow chamber of one of said blade arrangements;
- a converter circuit for conducting hydraulic fluid through said flow chambers of said blade arrangements and connected to a hydraulic fluid supply arrangement via a line system;
- and
- a choke element having a choke projection and movably mounted in said toroid so that said choke projection is operatively movable through said cutout and insertable into said flow chamber of said one of said blade arrangements for regulating a through-flow cross section of said flow chamber of said one of said blade arrangements, wherein said choke element comprises a carrier disk movably arranged within said toroid and receiving said choke projection via a connection ring extending toward said one of said blade arrangements.
A hydrodynamic torque converter, comprising:
- a pump wheel rotatably mounted about an axis of rotation;
- a turbine wheel rotatably mounted for rotating relative to said pump wheel about said axis of rotation;
- each said pump wheel and said turbine wheel comprising a blade arrangement forming flow chambers, said blade arrangements comprising stiffeners defining part of a toroid between said pump wheel and said turbine wheel;
- said toroid comprising a cutout adjacent a flow chamber of one of said blade arrangements;
- a converter circuit for conducting hydraulic fluid through said flow chambers of said blade arrangements and connected to a hydraulic fluid supply arrangement via a line system;
- and
- a choke element having a choke projection and movably mounted in said toroid so that said choke projection is operatively movable through said cutout and insertable into said flow chamber of said one of said blade arrangements for regulating a through-flow cross section of said flow chamber of said one of said blade arrangements, wherein said choke element comprises a cylinder connected to a control device via a control line and said choke projection comprises a piston rod projecting through said cutout.
