Beschreibung
Zusammenfassung:	A compressor unit (1) comprises a compressor (5) and a pressure meter (6). The pressure meter (6) comprises: a tubular body (18) communicating with the surge chamber (12B), a meter-piston (19) movable in the tubular body (18) in the longitudinal direction thereof by the compressed air, and a spring (20) biasing the piston 18 toward the front end. The tubular body (18) comprises a small diameter portion (18F) in which a seal ring (25) of the piston airtightly contacts with the tubular body, and a large diameter portion (18R) in which a gap (D) is formed between the seal ring and the tubular body. The large diameter portion is connected to the small diameter portion via a step (K) at which the insider diameter of the tubular body (18) is abruptly changed, whereby when the compressed air reaches to a specified pressure and the seal ring of the piston is moved beyond the step (K), the compressed air is discharged through the gap (D).
