摘要： The present disclosure relates to air assemblies having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, the present disclosure relates to air assemblies where the configuration of the air assembly can be changed manually by a user by operating a directional control valve to inflate, deflate, or close the inflatable product. The directional control valve may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.

摘要： A blower assembly includes a fan including a front plate that defines a fan inlet. The blower assembly also includes an inlet plate positioned adjacent the fan such that the inlet plate and the front plate define a cavity therebetween that extends circumferentially about the fan inlet. A motor is coupled to the fan and to the inlet plate and configured to rotate about the rotational axis. The motor is positioned within the cavity.

摘要： There is provided a nozzle for a fan assembly. The nozzle comprises an air inlet, a first air outlet and a second air outlet that are oriented in convergent directions, and a valve for controlling the first and second air outlets. The valve comprises one or more valve members that are moveable to simultaneously adjust the size of the first air outlet and inversely adjust the size of the second air outlet. The nozzle further comprises a third air outlet and a fourth air outlet, the third air outlet being opposite the fourth air outlet, the third and fourth air outlets being oriented in convergent directions, and the third air outlet and the fourth air outlet each being substantially perpendicular to each of the first and second air outlets.

摘要： A fan assembly includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A stator assembly (28) is located downstream of the fan rotor (18), relative to an airflow (14) direction through the fan assembly. The stator assembly (28) includes a plurality of stator vanes (30) extending between a stator hub (32) and a stator shroud (34). A flow control ring (36) is positioned between the fan rotor (18) and the stator assembly (28) to block radial flow migration in an axial spacing between the fan rotor and the stator assembly resulting from a radial flow component of an airflow (14) exiting the fan rotor (18).

摘要： An electric propulsion assembly for an aircraft includes a nacelle having a nacelle cowl which defines an inner space for arranging an electric propulsion unit, which includes a blower, of the aircraft. An electric motor assembly is placed in the inner space and connected to the propulsion unit to supply power to the propulsion unit. An airflow generated by the blower flows in a space between the motor assembly and the nacelle cowl defining a duct to supply thrust to the aircraft. A power electronics system has at least one heat exchanger to transfer thermal energy from the system to a work fluid to cool the system. The heat exchanger is placed to project at least partially into the duct, so that the work fluid consists of the air flow generated by the blower.
