Abstract
A compressor element (1) comprising at least one compression member (2), a housing (3) and a rotatable shaft (4) rotatably connecting the at least one compression member (2) to the housing (3), wherein at least one intermediate element (5) is provided between the rotatable shaft (4) and the housing (3) for facilitating rotation of the rotatable shaft (4), wherein the compressor element (1) further comprises at least one oil injector (6) extending from an inlet port (7) to at least one nozzle (8a, 8b, 8c) via an oil channel (9), wherein the oil channel (9) is shaped to allow a substantially primary flow of oil through the channel (9) for cooling of the at least one intermediate element (5).
Claims11
A compressor element (1) comprising at least one compression member (2), a housing (3) and a rotatable shaft (4) rotatably connecting the at least one compression member (2) to the housing (3), wherein at least one intermediate element (5) comprising at least one of a roller bearing and a gear is provided between the rotatable shaft (4) and the housing (3) for facilitating rotation of the rotatable shaft (4), wherein the compressor element (1) further comprises at least one oil injector (6) extending from an inlet port (7) to at least one nozzle (8a, 8b, 8c) via an oil channel (9), wherein the oil channel (9) is shaped with a radius of curvature (20) larger than 5 mm to allow a flow of oil through the channel (9) for cooling of the at least one intermediate element (5) which is aligned with a direction determined by a centre line of the oil channel (9).
A method for manufacturing a compressor element (1) comprising at least one compression member (2), a housing (3) and a rotatable shaft (4) rotatably connecting the at least one compression member (2) to the housing (3), the method comprises providing at least one intermediate element (5) comprising at least one of a roller bearing and a gear between the rotatable shaft (4) and the housing (3) for facilitating rotation of the rotatable shaft (4), the method further comprises providing the compressor element (1) with at least one oil injector (6) extending from an inlet port (7) to at least one nozzle (8a, 8b, 8c) via an oil channel (9), wherein the method further comprises:
- shaping the oil channel (9) with a radius of curvature (20) larger than 5 mm to allow a flow of oil through the channel (9) for cooling of the at least one intermediate element (5) which is aligned with a direction determined by a centre line of the oil channel (9).
