Abstract: A container holder/tray combination includes a housing for mounting to a vehicle. The housing defines a recess for receiving therein at least one container holder, a cover pivotally mounted to the housing for covering the container holder and housing when in a closed position, and movable to an open position. The cover has a surface defining a tray, and the container holder is movably mounted with respect to the housing and tray between a first position coplanar with the tray for positioning a container therein and a second position within the housing. In a preferred embodiment, multiple independently movable adjacent container holders are provided to allow selectable use of the tray area.

Abstract: A system for cooling a turbo compressor includes two compressing parts on opposite ends of a rotational shaft driven by a motor. Fluid from a fluid chamber within the casing of the device is supplied to a bearing chamber when the temperature of the bearing chamber increases. A supply passage is formed in a first support where the radial bearing for supporting a load in the axial direction is formed. The open-and-shut valve supplies fluid when the temperature of the bearing chamber increases.
