Abstract
A pressure indicator for indicating pressure of a pressure source. The indicator comprises a first reservoir which defines a first enclosed volume having a first inlet pipe for communication between the first enclosed volume and a first source of pressurised fluid. A damping passage is provided in fluid communication with the first enclosed volume. A pressure oscillation damping means is provided in the damping passage. The damping means comprises a moveable body constrained within a limited range of motion along the damping passage.
Claims20
A pressure indicator for indicating pressure of a pressure source, the indicator comprising:
- a first reservoir which defines a first enclosed volume having a first inlet pipe for communication between the first enclosed volume and a first source of pressurised fluid, and
- a damping passage is provided in fluid communication with the first enclosed volume, wherein
- a pressure oscillation damper is provided in the damping passage, the damper providing a seal in the damping passage such that there is no fluid flow around the damper, and the damper including a moveable body constrained within a limited range of motion along the damping passage.
A pressure indicator for indicating pressure of a first source of pressurised fluid, the indicator comprising:
- a first reservoir defining a first enclosed volume including:
- a first inlet pipe for fluid communication between the first enclosed volume and the first source of pressurised fluid;
- a damping passage that is in fluid communication with the first enclosed volume of the first reservoir;
- and
- a pressure oscillation damper disposed in the damping passage, the pressure oscillation damper including a moveable body constrained within a limited range of motion along the damping passage, and the pressure oscillation damper being configured to form a seal in the damping passage such that fluid does not flow past the damper.
A pressure indicator for indicating pressure of a first source of pressurised fluid and a second source of pressurised fluid, the indicator comprising:
- a first reservoir defining a first enclosed volume including:
- a first inlet pipe for fluid communication between the first enclosed volume and the first source of pressurised fluid;
- a second reservoir defining a second enclosed volume including:
- a second inlet pipe for fluid communication between the second enclosed volume and the second source of pressurised fluid;
- a damping passage that is in fluid communication with the first enclosed volume of the first reservoir and the second enclosed volume of the second reservoir;
- and
- a pressure oscillation damper disposed in the damping passage, the pressure oscillation damper including a moveable body constrained within a limited range of motion along the damping passage, and the pressure oscillation damper being configured to form a seal in the damping passage such that fluid does not flow past the damper.
