Abstract
An assembly can include a valve seat for an exhaust bypass valve of a serial turbocharger system where the valve seat includes a base portion and a wall portion that extends axially away from the base portion; and a gasket that includes a planar portion that defines a perimeter and a socket disposed interior to the perimeter, where the socket includes a valve seat surface axially recessed from the planar portion and configured to position the seat. In various examples, the valve seat is positioned in the socket of the gasket and fixed to the gasket. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
Claims20
An assembly comprising:
- a valve seat for an exhaust bypass valve of a serial turbocharger system wherein the valve seat comprises a base portion and a wall portion that extends axially away from the base portion;
- and
- a gasket that comprises a planar portion that defines a perimeter and a socket disposed interior to the perimeter, wherein the socket comprises a valve seat surface axially recessed from the planar portion and configured to position the valve seat.
An assembly for a serial sequential turbocharger system, the assembly comprising:
- an exhaust bypass valve that comprises an arm and a poppet;
- a housing that comprises an exhaust chamber configured to house the exhaust bypass valve;
- a component configured for attachment to the housing wherein the component comprises an exhaust passage;
- and
- a valve seat fixed to a gasket disposed between the housing and the component wherein the gasket positions the valve seat with respect to the poppet for an orientation of the exhaust bypass valve that seals the exhaust chamber from the exhaust passage.
A method comprising;
- providing a valve seat and a gasket that comprises a socket configured for receipt of the valve seat;
- positioning the valve seat with respect to the socket of the gasket;
- fixing the valve seat to the gasket;
- joining a housing and another component with the gasket and valve seat disposed therebetween to locate the valve seat with respect to an exhaust bypass valve housed by the housing;
- and
- sealing an exhaust chamber of the housing from an exhaust passage of the component by contacting the valve seat and the exhaust bypass valve.
