Title:
真空を生むためのベンチュリデバイスのベンチュリギャップ内のバルブゲート
Document Type and Number:
Japanese Patent JP7008691
Kind Code:
B2
Abstract:
Venturi devices are disclosed herein that include a body defining a Venturi gap between an outlet end of a converging motive section and an inlet end of a diverging discharge section, having a suction port in fluid communication with the Venturi gap, a gate valve linearly translatable to open and close the Venturi gap, and an actuator connected to the gate valve to operatively move the gate valve between an open position and a closed position. The gate valve, in a longitudinal cross-section, is generally U-shaped, thereby having continuous, opposing sides that one each close the motive outlet and the discharge inlet and defining a void between the opposing sides that is in fluid communication with the suction port. The converging motive section defines a circular-shaped motive inlet and defines an elliptical- or polygonal-shaped motive outlet, and the diverging discharge section defines an elliptical- or polygonal-shaped discharge inlet.
