Document Type and Number:
WIPO Patent Application WO/2012/132047
Kind Code:
A1
Abstract:
An ejector (20) built in an ejector housing hole (18) comprises a nozzle (21) for diffusing and ejecting compressed air from an air supply port (23), and a diffuser (22) in which an ejection port (29) for discharging air ejected from the nozzle (21) and air flowing in from a suction port (30) is formed. A sound dampening chamber (43) is formed in a muffler body (42) attached to an ejector block (11), and an exhaust port (48) is formed in a leading end wall portion (42b) of the muffler body (42) on the reverse side from the ejection port (29). The sound dampening effect can be achieved while the degree of vacuum of negative-pressure air and the suction flow rate are ensured by discharging air from the exhaust port (48).
