Abstract

There is provided a pneumatic booster having an ejector, which achieves space-saving and enables easy piping. An ejector 4 is provided within a constant-pressure chamber 3 formed in an outer shell 2. A connecting pipe 19 communicated with an outlet of a diffuser and a connecting pipe communicated with an inlet of a nozzle extend outward of the shell, and a suction port is open to the inside of the constant-pressure chamber 3 through a check valve. The connecting pipe 19 is communicated with the constant-pressure chamber 3 through a check valve 10, and is connected to a suction pipe of an engine (a source of a negative pressure). The connecting pipe on the inlet side of the nozzle is connected to an air cleaner (the atmosphere). A negative pressure is directly supplied from the connecting pipe 19 to the constant-pressure chamber 3 through the check valve 10. The ejector 4 is operated to supply a high degree of vacuum to the constant-pressure chamber 3 through the suction port. The ejector 4 is provided within the constant-pressure chamber 3 so as to achieve space-saving. The check valve 10 is provided in the ejector 4 and the connecting pipe 19 is extended outward of the shell, so as to enable easy piping.
