A compressor device includes a motor cooling system that provides a first flow of a first fluid through a housing for cooling a motor. The motor cooling system includes a first fluid flow section at a first axial position. The first fluid flow section extends in a downstream direction radially with respect to the axis of rotation. Also, the device includes a bearing cooling system that provides a second flow of a second fluid through the housing for cooling the bearing. The bearing cooling system includes a second flow section at a second axial position that is spaced apart axially from the first axial position. The second flow section extends in a downstream direction radially with respect to the axis of rotation. The first flow section and the second flow section are disposed in a heat exchanger arrangement configured to transfer heat between the second fluid and the first fluid.

An assembly can include a turbine housing that includes a bore, a wastegate seat and a wastegate passage that extends to the wastegate seat; a bushing disposed at least in part in the bore; a rotatable wastegate shaft received at least in part by the bushing; a wastegate plug that extends from the wastegate shaft; a control arm operatively coupled to the wastegate shaft; a control link operatively coupled to the control arm; a pin that forms a joint between the control arm and the control link; and a biasing element coupled to the pin and to the control link.

A method includes positioning a bushing in a bore of a turbine housing; positioning a shaft of a wastegate in a bore of the bushing where the shaft includes a shaft shoulder and a shaft end; applying force to a plug of the wastegate to substantially center the plug with respect to a wastegate seat of the turbine housing; positioning a resilient metal wire mesh ring at least in part in the bore of the bushing and between the shaft shoulder and the shaft end; encasing the ring into the bore of the bushing; and fixing a control arm to the shaft.

Method of assembling a turbine wastegate assembly

An assembly can include a turbine housing that includes a bore, a wastegate seat and a wastegate passage that extends to the wastegate seat; a bushing configured for receipt by the bore; a rotatable wastegate shaft configured for receipt by the bushing; a wastegate arm extending from the wastegate shaft; and a wastegate plug extending from the wastegate arm where the wastegate plug includes a profile, defined in part by a portion of a torus, for contacting the wastegate seat to cover the wastegate passage and, for example, defined in part by a portion of a modified sphere or a portion of a cone. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
