Abstract
Official abstract text for this publication.
A jet engine includes a hollow shaft, a center bent tube which is inserted into the shaft, an annular support portion which protrudes from an inner wall surface of the shaft, and an annular spacer ring which is provided on an outer wall surface of the center bent tube and slidably abuts on the support portion, in which the spacer ring includes an outer circumferential surface which has a shape along a surface of the support portion in an axial direction of the shaft, an inner circumferential surface which has a shape along the outer wall surface of the center bent tube in the axial direction of the shaft, and a cut portion in which a portion of the spacer ring is cut.
First claim
Opening claim text (preview).
What is claimed is: 1 . A jet engine, comprising: a hollow shaft; a center bent tube which is inserted into the shaft; an annular support portion which protrudes from an inner wall surface of the shaft; and an annular spacer ring which is provided on an outer wall surface of the center bent tube and slidably abuts on the support portion, wherein the spacer ring includes an outer circumferential surface which has a shape along a surface of the support portion in an axial direction of the shaft, an inner circumferential surface which has a shape along the outer wall surface of the center bent tube in the axial direction of the shaft, and a cut portion in which a portion of the spacer ring is cut. 2 . The jet engine according to claim 1 , wherein both ends of the outer circumferential surface of the spacer ring in the axial direction of the shaft are chamfered. 3 . The jet engine according to claim 1 , wherein the cut portion is linearly provided to be inclined to the axis of the shaft. 4 . The jet engine according to claim 2 , wherein the cut portion is linearly provided to be inclined to the axis of the shaft. 5 . The jet engine according to claim 1 , wherein the center bent tube includes an annular accommodation groove in which the spacer ring is accommodated, and wherein wall surfaces of the accommodation groove facing each other in the axial direction of the shaft are disposed with a gap with respect to the spacer ring. 6 . The jet engine according to claim 2 , wherein the center bent tube includes an annular accommodation groove in which the spacer ring is accommodated, and wherein wall surfaces of the accommodation groove facing each other in the axial direction of the shaft are disposed with a gap with respect to the spacer ring. 7 . The jet engine according to claim 3 , wherein the center bent tube includes an annular accommodation groove in which the spacer ring is accommodated, and wherein wall surfaces of the accommodation groove facing each other in the axial direction of the shaft are disposed with a gap with respect to the spacer ring. 8 . The jet engine according to claim 4 , wherein the center bent tube includes an annular accommodation groove in which the spacer ring is accommodated, and wherein wall surfaces of the accommodation groove facing each other in the axial direction of the shaft are disposed with a gap with respect to the spacer ring. 9 . The jet engine according to claim 1 , wherein a gap is formed between the center bent tube and the support portion. 10 . The jet engine according to claim 2 , wherein a gap is formed between the center bent tube and the support portion.
