An exhaust gas treatment device for internal combustion engines and the like includes inlet and outlet end caps, two catalyst substrates, and a two-piece housing. A first, cylindrically-shaped housing member has a hollow interior in which one of the substrates is retained, a first end sealingly connected with the inlet end cap, and an opposite second end with a radially reduced section. A second cylindrically-shaped housing member has a hollow interior in which the other one of the substrates is retained, a first end sealingly connected with the outlet end cap, and an opposite second end with a radially enlarged section sized to receive therein the second end of the first housing member, whereby the reduced section of the first housing member and the enlarged section of the housing member are spaced radially apart a predetermined distance to define an annularly-shaped space or gap which thermally insulates the associated portion of the exhaust gas treatment device.

Exhaust gas treatment device with insulated housing construction

A speed-responsive engaging mechanism adapted for use in a hydrodynamic device to couple turbine and impeller members including a disc secured to the turbine member having a series of convexly curved cam surfaces thereon formed in apertures in the discs with a series of friction shoe assemblies mounted in the apertures in engagement with the cam surfaces. The friction shoe assemblies engage with the impeller at a predetermined speed of rotation of the turbine member, and the curved cam surface induces a wedging engagement of the shoes with the impeller member. Spring means are provided to retain the shoe assemblies in the apertures, and a roller mechanism is provided in each shoe assembly to provide relatively frictionless relative movement between the cam surfaces and the shoe assemblies. Each shoe in the assembly is made of a sintered metal material and has a spring retaining structure cast in the shoe.
