An electric compressor includes a rotation shaft, a compressor impeller, a rotor portion, a stator portion, and a motor housing. The motor housing includes an inner housing which includes a first cylindrical portion surrounding and holding the stator portion and an outer housing which includes a second cylindrical portion surrounding and holding the first cylindrical portion of the inner housing. An outer peripheral surface of the stator portion is in contact with an inner peripheral surface of the first cylindrical portion of the inner housing. An outer peripheral surface of the first cylindrical portion is provided with a first groove portion disposed to turn around an axis of the rotation shaft by one turn or more and the first groove portion includes a spiral groove portion.

An exhaust gas energy recovery device includes a power generation device driven by a turbine configured to rotate by an exhaust gas, a switching element connected to the power generation device, a first terminal connected to the power generation device via the switching element and for being connected to a first power storage device, and a second terminal connected to the power generation device and for being connected to a second power storage device, in which a terminal voltage of the first power storage device is lower than a terminal voltage of the second power storage device, and the switching element switches a destination to be charged by the power generation device to either the first power storage device or the second power storage device on the basis of magnitude of a direct current voltage output from the power generation device.

Exhaust gas energy recovery device

An electric turbocharger includes an electric motor which rotationally drives a rotating blade, a motor housing which accommodates the electric motor therein, a controller which is disposed outside the motor housing and controls the driving of the electric motor, and a power supply mechanism which supplies a current from the controller to the electric motor through a through-hole communicating the inside and the outside of the motor housing, in which the power supply mechanism includes a rod which is hermetically sealed while being inserted through the through-hole, a connector which is connected to at least one end of the rod, and a busbar which is connected to the connector, and in which the connector absorbs a relative positional displacement of the rod with respect to the connector.

Electric turbocharger

A rotary machine is provided with: a bearing that supports a rotary shaft of an impeller; a bearing support part that supports an outer circumference of the bearing; a key groove that is formed in the bearing and the bearing support part and extends along a rotary shaft line direction of the rotary shaft; and a key member that is inserted into the key groove. The bearing support part is provided with an outer regulating part that can contact one end part of the key member inside the key groove. An outer ring of the bearing is provided with an inner regulating part that can contact another end part of the key member inside the key groove. A distance between the outer regulating part and the inner regulating part is longer than a length of the key member in the rotary shaft line direction.

Rotary machine

A seal structure includes a rotary shaft that is provided inside a housing, a metal-made surrounding portion of the housing that surrounds the rotary shaft in a radial direction of the rotary shaft, and a resin-made seal member that faces an inner circumferential surface of the surrounding portion and rotates together with the rotary shaft.
