Patent number: 10220396Abstract: A nozzle pipe is to be coupled to a distal open end of an air blow-off tube of a blower apparatus for regulating the profile of an airflow blown out from the blow-off tube. The nozzle pipe comprises an outer tubular member and an inner tubular member coaxially disposed within the outer tubular member. The inner tubular member has a circumferential wall formed with apertures allowing air passage therethrough. The outer tubular member and the inner tubular member provides a first space therebetween to form a first air passage, while the inner tubular member provides a second space therein to form a second air passage. A plurality of rectifier fins are disposed inward from the outer tubular member, standing radially and extending longitudinally, and spaced apart circumferentially from each other. The fins extend inclined at an angle with reference to the longitudinal central axis of the tubular members.Type: GrantFiled: June 19, 2015Date of Patent: March 5, 2019Assignee: MAKITA CORPORATIONInventors: Shinsuke Naka, Tomonobu Nashimoto, Yoshinori Shibata
