Abstract
Abstract The adjusting cylinder is moved axially by a pair of servomotors mounted on the casing exterior via piston rods which pass into the casing interior is seal-tight manner. Connecting rods having ball-headed ends connect the piston rods to the cylinders to compensate for radial movements of the adjusting cylinder relative to the casing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
In an axial compressor a casing defining a gas-tight internal chamber; an adjusting cylinder for stator blades axially slidably mounted in said internal chamber within said casing; a pair of linear servomotors mounted on said casing exteriorly of said internal chamber, said servomotors being operatively connected in parallel relationship with each other, each said servomotor having a piston rod extending through said casing into said internal chamber; a seal disposed on each piston rod for sealingly mounting each piston rod in said casing; and a pair of connecting rods, each said connecting rod coupling one said piston rod to said adjusting cylinder, each said connecting rod having a ball head at each end rotatably received in a respective piston rod and in said adjusting cylinder.
Claim 2
Dependent Claim
125 words
In an axial compressor a casing defining a gas-tight internal chamber; an adjusting cylinder for stator blades axially slidably mounted in said internal chamber within said casing; a pair of linear servomotors mounted on said casing exteriorly of said internal chamber, said servomotors being operatively connected in parallel relationship with each other, each said servomotor having a piston rod extending through said casing into said internal chamber; a seal disposed on each piston rod for sealingly mounting each piston rod in said casing; and a pair of connecting rods, each said connecting rod coupling one said piston rod to said adjusting cylinder, each said connecting rod having a ball head at each end rotatably received in a respective piston rod and in said adjusting cylinder.
Claim 3
Dependent Claim
50 words
In an axial compressor as set forth in claim 1, an extension sleeve mounted on each respective piston rod and projecting therefrom through said casing with a respective said seal thereon, each said piston rod being of a length corresponding to the length of stroke of a respective said servomotor.
Claim 4
Dependent Claim
29 words
In an axial compressor as set forth in claim 1, each said seal being mounted in said casing for guiding each respective piston rod for an axially centered motion.
Claim 5
Dependent Claim
113 words
In an axial compressor, a casing defining a gas-tight internal chamber; an adjusting cylinder for stator blades axially slidably mounted in said internal chamber within said casing; means mounted on said casing, exteriorly of said internal chamber, for moving said adjusting cylinder axially relative to said casing, said means including at least one servomotor having a piston rod and a connecting rod coupling said piston rod to said adjusting cylinder, said connecting rod being rotatably received in said piston rod and said adjusting cylinder so as to form a universal joint at either end thereof; and sealing means sealing said piston rod relative to said casing to form a gas tight seal therebetween.
Claim 6
Dependent Claim
113 words
In an axial compressor, a casing defining a gas-tight internal chamber; an adjusting cylinder for stator blades axially slidably mounted in said internal chamber within said casing; means mounted on said casing, exteriorly of said internal chamber, for moving said adjusting cylinder axially relative to said casing, said means including at least one servomotor having a piston rod and a connecting rod coupling said piston rod to said adjusting cylinder, said connecting rod being rotatably received in said piston rod and said adjusting cylinder so as to form a universal joint at either end thereof; and sealing means sealing said piston rod relative to said casing to form a gas tight seal therebetween.
Claim 7
Dependent Claim
41 words
In an axial compressor as set forth in claim 4, said piston rod including an extension sleeve thereon projecting into said casing and having said sealing means thereon, said connecting rod being disposed concentrically within said sleeve in spaced radial relation.
