Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

Abstract: An air blowing device includes a duct portion and a passage variable device. The duct portion forms a main passage through which an air flow passes, and an outlet is defined downstream of the main passage to blow out the air flow. The passage variable device is configured to change a passage area of the main passage so that the air flow becomes a pulsating flow and is blown out from the outlet.

Abstract: A screw pump includes a male screw, a female screw, a motor, a journal, a bearing member, and a case. The motor includes an output shaft, which transmits a torque to the male screw, and the motor is operable to drive the male screw to rotate the same through the output shaft. The journal is rotatably placed between the output shaft of the motor and the male screw. The bearing member rotatably supports the journal. The case includes a screw receiving hole that receives the male screw and the female screw. The journal and the male screw are coaxially and non-detachably integrated together. The output shaft and the journal are fitted together by clearance fit that enables transmission of the torque between the output shaft and the journal.

Abstract: A cooling device includes: a pump arranged to supply air at a position separated from a space where a wind flows; and a front grille arranged in an introduction port where the wind is introduced. The front grille is located at a position opposing a radiator, and includes at least one support component having a hollow shape in which air is able to flow. A discharge part of the pump is connected to the support component such that air discharged from the discharge part flows into an interior space of the support component. The support component has an air blow-out part at a position opposing the radiator to blow out air which flows inside of the support component.

Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.

Abstract: A screw pump has a male screw accommodation hole and a female screw accommodation hole formed in a pump housing. A male screw member and a female screw member are respectively accommodated in the male screw accommodation hole and the female screw accommodation hole. A male-side clearance is formed in a radial direction between the male screw member and the male screw accommodation hole and a female-side clearance is formed in the radial direction between the female screw member and the female screw accommodation hole. The female-side clearance is made to be larger than the male-side clearance, so that the female screw member can easily move in a direction away from the male screw member to the female-side clearance when any extraneous material is going to be wedged between the male screw member and the female screw member, to thereby prevent a locked condition of the screw members.
