Abstract
A turbine housing includes a wastegate chamber with a wastegate opening; and a wastegate disposed in the wastegate chamber where the wastegate includes a plug configured to plug the wastegate opening and where the plug includes a surface; a shaft configured for receipt by a bore in a wall of the wastegate chamber; and a rotatable arm extending from the shaft where the arm has a surface configured for contacting the surface of the plug for a closed orientation of the plug with respect to the wastegate opening to transmit force from the arm more centrally to the plug. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
Claims20
A wastegate assembly comprising:
- a plug configured to plug a wastegate opening wherein the plug comprises a peg extending from a planar surface;
- a shaft configured for receipt by a bore in a wastegate chamber;
- and
- a rotatable arm extending from the shaft wherein the arm comprises a peg opening configured for receipt of the peg of the plug and wherein the arm comprises a lower surface that comprises a beveled portion, the lower surface configured to contact the planar surface of the plug for a closed orientation of the plug with respect to the wastegate opening.
A wastegate assembly comprising:
- a plug configured to plug a wastegate opening wherein the plug comprises a peg extending from a rounded surface;
- a shaft configured for receipt by a bore in a wastegate chamber;
- and
- a rotatable arm extending from the shaft wherein the arm comprises an annular, beveled lower surface leading to a peg opening configured for receipt of the peg of the plug, the annular, beveled lower surface configured to contact the rounded surface of the plug for a closed orientation of the plug with respect to the wastegate opening.
A wastegate assembly comprising:
- a plug configured to plug a wastegate opening wherein the plug comprises a concave, at least partially spherical surface;
- a shaft configured for receipt by a bore in a wastegate chamber;
- and
- a rotatable arm extending from the shaft wherein the arm comprises a convex, at least partially spherical surface configured for contacting the concave, at least partially spherical surface of the plug for a closed orientation of the plug with respect to the wastegate opening.
