Abstract
A system for damping pressure pulses is provided, including a channel for permitting fluid flow between a first chamber and a second chamber, a piston for varying a fluid flowing space such that pressure pulses in fluid are damped, and a flexible wall for absorbing pressure pulses in fluid, wherein the flexible wall is connected to the piston by a transmitting rod such that a movement of the piston results in a deformation of the flexible wall and vice versa.
Claims38
A system for damping pressure pulses, comprising:
- a channel for permitting fluid flow between a first chamber and a second chamber;
- a piston for varying a fluid flowing space such that pressure pulses in fluid are damped, wherein the piston varies the fluid flowing space by changing an annular space;
- and
- a flexible wall for absorbing pressure pulses in fluid, wherein the flexible wall is connected to the piston by a transmitting rod such that a movement of the piston results in a deformation of the flexible wall and vice versa.
A method for damping pressure pulses in a fluid with a pressure pulse damping system, comprising the steps of:
- using a throat nozzle for permitting fluid flow between a first chamber and a second chamber;
- using a piston for varying a fluid flowing space such that pressure pulses in fluid are damped, wherein the piston varies the fluid flowing space by changing an annular space;
- and
- using a flexible wall for absorbing pressure pulses in fluid, wherein the flexible wall is connected to the piston by a transmitting rod such that a movement of the piston results in a deformation of the flexible wall and vice versa.
A method for assembling a pressure pulse damping system, comprising the steps of:
- installing in a housing a throat nozzle for permitting fluid flow between a first chamber and a second chamber;
- installing in the housing a piston for varying a fluid flowing space such that pressure in fluid is damped, wherein the piston varies the fluid flowing space by changing an annular space;
- and
- installing in the housing a flexible wall for absorbing pressure pulses in fluid, wherein the flexible wall is connected to the piston by a transmitting rod such that a movement of the piston results in a deformation of the flexible wall and vice versa.
