Abstract
Abstract The reservoir has three fastening elements, on the upper part of the reservoir and the two others on the lower part of opposed end faces. The fastening elements are provided at the ends of an axle mounted in elastic support means and in a tubular passage parallel to the adjacent face of the housing and parallel to the axis of the turbojet engine, secured to the reservoir and passing through it from end to end.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
227 words
An oil reservoir with an antivibration suspension to be fastened to the housing of a turbojet engine, characterized in that the reservoir is in the form of a volume inscribed approximately in the frustum of a quadrangular prism having two large opposing faces (3, 4), one of which (3) is located concentrically to the housing and in its vicinity, and interconnected by means of end faces (10, 11) and upper (5) and lower (6) faces parallel to the axis of the turbojet engine, said reservoir having a fastening element (7) at the upper part of the reservoir and two fastening elements (8, 9) on the lower part of the end faces (10, 11) carried by the ends of an axle (12) which extends parallel to the axis of the turbojet engine, passing through the reservoir from end to and mounted in elastic support means within a tubular passage (13) which also extends through the reservoir, said elastic support means consisting of at least two sleeves (27) of an elastic material, surrounding the axle (12) and being maintained spaced apart by means of a tubular spacer (28) on the axle (12) which spacers has circular stops (29), abutting against end surfaces of the sleeves (27), and means for the axial displacement (30, 31) of the sleeves and the spacer being provided at one end of the axle (12).
Claim 2
Dependent Claim

An oil reservoir with an antivibration suspension to be fastened to the housing of a turbojet engine, characterized in that the reservoir is in the form of a volume inscribed approximately in the frustum of a quadrangular prism having two large opposing faces (3, 4), one of which (3) is located concentrically to the housing and in its vicinity, and interconnected by means of end faces (10, 11) and upper (5) and lower (6) faces parallel to the axis of the turbojet engine, said reservoir having a fastening element (7) at the upper part of the reservoir and two fastening elements (8, 9) on the lower part of the end faces (10, 11) carried by the ends of an axle (12) which extends parallel to the axis of the turbojet engine, passing through the reservoir from end to and mounted in elastic support means within a tubular passage (13) which also extends through the reservoir, said elastic support means consisting of at least two sleeves (27) of an elastic material, surrounding the axle (12) and being maintained spaced apart by means of a tubular spacer (28) on the axle (12) which spacers has circular stops (29), abutting against end surfaces of the sleeves (27), and means for the axial displacement (30, 31) of the sleeves and the spacer being provided at one end of the axle (12).
Claim 3
Dependent Claim
33 words
An oil reservoir according to claim 1 wherein the end faces (10, 11) have cylindrical flanges (25, 24) through which pass and to which are secured the ends of the tubular passage (13).
Claim 4
Dependent Claim
77 words
An oil reservoir according to claim 1 wherein it contains at least one internal partition (15) perpendicular to the large opposing faces (3, 4), secured to the ribs (14) carried by the internal walls of the large opposing faces (3, 4) in a plane perpendicular to the faces (3, 4), said partition containing its lower part an orifice (19) equipped with a cylindrical flange (20) through which passes and to which is secured the tubular passage (13).
Claim 5
Dependent Claim
35 words
An oil reservoir according to claim 2 or claim 3 wherein the elastic sleeves (27) are of a length approximately equal to that of the cylindrical flange and are positioned in the tubular passage (13).
Claim 6
Dependent Claim
31 words
An oil reservoir according to claim 1 wherein the axle (12) has at least one collar (32) forming the circular stop for one of the terminal surfaces of an elastic sleeve.
Claim 7
Dependent Claim
47 words
An oil reservoir according to claim 3 wherein internal partitions (15) forms, in relation to the upper (5) and lower (6) surfaces, the free spaces allowing the balancing of the oil levels and the partitions having a plurality of holes (18) for the circulation of the oil.
Claim 8
Dependent Claim
43 words
An oil reservoir according to claim 1 wherein the upper face (5) of the reservoir contains an orifice providing for the inspection of welds and for cleaning and the border of which defines a flat support surface (3) to receive a cover (34).
Claim 9
Dependent Claim
83 words
An oil reservoir according to claim 1 wherein the fastening element (7) provided on the upper part of the reservoir consists of a strap secured to the reservoir and receiving an axle cooperating with one end of a link (40), the other end whereof cooperates with a strap fastening to the housing of the engine and in that the fastening elements (8, 9) located on the lower part of the reservoir cooperate with straps (42, 41) secured to the housing of the engine.
