Title:
低い圧力差のもとで流速を制限するための装置
Document Type and Number:
Japanese Patent JP4702815
Kind Code:
B2
Abstract:
The flow channel (23) cross section between flexible walls (17, 18), is a function of pressure differential between the suction inlet and outlet openings (14, 15) of the casing (11). Flexibility of the wall material can be varied to control the maximal volumetric flow rate of inhalation. The flow channel has a lengthy, planar cross section (a x b) formed by opposite large-area walls. These are externally-open to the surroundings, at least near the center. The surrounding chambers (24, 25) each have a hole for this purpose. The flow channel is layered.
