Abstract
Abstract A device for the transformation of a fluid pressure, that is to say of the pressure of a liquid, a vapor, or a gas, into a motion capable of performing mechanical work, which comprises a pressurizable variable capacity chamber. This chamber is wholly or partly formed by a bag-shaped diaphragm which is elastically stretchable in preferably only one direction and attached to at least two rigid relatively movable members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A device for the transformation of a fluid pressure into a motion capable of performing mechanical work, comprising a pressurizable variable capacity chamber formed at least partly by a bag-shaped diaphragm which is elastically stretchable in preferably only one direction and defining a substantially toroidal variable capacity chamber and being provided with stiffening elements extending obliquely across the radial direction, the diaphragm being attached at its outside periphery to a fixed or movable rigid member and at its inner edge to a correspondingly fixed or movable rigid member.
Claim 2
Independent Claim
88 words
A device for the transformation of a fluid pressure into a motion capable of performing mechanical work, comprising a pressurizable variable capacity chamber formed at least partly by a bag-shaped diaphragm which is elastically stretchable in preferably only one direction and defining a substantially toroidal variable capacity chamber and being provided with stiffening elements extending obliquely across the radial direction, the diaphragm being attached at its outside periphery to a fixed or movable rigid member and at its inner edge to a correspondingly fixed or movable rigid member.
Claim 3
Dependent Claim
29 words
A device according to claim 1, wherein the diaphragm is provided with inelastic stiffening elements which prevent the diaphragm from elastically stretching in the lengthwise direction of these elements.
Claim 4
Dependent Claim
17 words
A device according to claim 1, wherein the diaphragm is a bellows made of an inelastic material.
Claim 5
Dependent Claim
21 words
A device according to claim 3, wherein at least one side of the bellows is provided with a sealing elastic material.
Claim 6
Dependent Claim
33 words
A device according to claim 2, wherein the diaphragm forms a substantially tubular connection between the rigid members and the stiffening elements embrace the diaphragm in the form of girth rings or helix.
Claim 7
Dependent Claim
32 words
A device according to claim 2, wherein the diaphragm forms a substantially tubular connection between the rigid members and the stiffening elements extend approximately in the axial direction of the tubular connection.
Claim 8
Dependent Claim
40 words
A device according to claim 6, wherein the substantially tubular connection contains substantially parallel axially disposed stiffening elements and defines an internal and a surrounding closed chamber which can be pressurized by the introduction thereinto of a fluid under pressure.
Claim 9
Dependent Claim
17 words
A device according to claim 1, wherein the inelastic stiffening elements are in the form of filaments.
