摘要： A pressure pulsation trap is provided. The pressure pulsation trap includes a channel extending from an inlet to an outlet, and a plurality of branches extending from the channel, each of the branches having different lengths than one another. The different lengths are configured such that the branches attenuate noise and/or vibration over a range of operating frequencies.

摘要： A drainage system, comprising a collector which is arranged to collect liquid and a drainage pipe having a pipe inlet that opens into the collector such that liquid collected by the collector drains through the pipe inlet. The drainage pipe is provided with a vent spaced away from the pipe inlet. The vent is arranged such that, when liquid collected by the collector occludes the pipe inlet, liquid flowing through the drainage pipe draws air into the drainage pipe through the vent.

摘要： A method of repairing a section of a pipe including a breach in the pipe. A surface of a wall of the pipe is prepared generally around the breach. A piece of conformable material of the type capable of carrying a curable polymer is sized in relation to a size of the breach. The sized piece of conformable material is applied to the prepared surface so that the breach is covered by the piece of conformable material. The piece of conformable material is impregnated with a curable polymer. The curable polymer is cured within the piece of conformable material thereby to seal the breach against egress of groundwater into the pipe.

摘要： A method is provided for actively compensating for pressure changes of a working fluid within a conduit. A first cavity is provided in fluid communication with the conduit. A second cavity is in fluid communication with a control fluid. A plunger is in communication with both the first cavity and the second cavity and is movable in response to pressure changes of the working fluid in the conduit. The plunger is re-centered. Re-centering the plunger includes the following steps. Position data representative of movement of the plunger is collected. The position data is analyzed with a control unit to determine an average position of the plunger which is offset relative to a center position. The average position of the plunger is compared, with a control unit, to the center position. A signal is relayed from the control unit to a control valve to urge the plunger toward the center position.

摘要： An in-line water hammer arrester comprises a housing connectable at each end to a piping system, a fluid channel disposed within the housing to permit fluid to flow from the piping system through the housing and back into the piping system, a piston and a pressurized chamber. When a pressure spike occurs, the piston is pushed against the pressurized chamber allowing an expanded area for water flow until the pressure spike is dissipated and the piston returns to its resting position. When used with flexible hoses and tubing typically found with household appliance water supply lines, the in-line arrester is easily installed by a crimping or clamping type connector and takes up little space.

摘要： An overpressure absorption mechanism is provided for a fluid bed processor. The mechanism includes spring assemblies mounted in the legs of the processor. The arms of the lower housing section extend into the legs and are supported on the springs. If an overpressure condition arises within the processor, the springs compress to allow movement between the housing sections to allow engagement of clamping rings which contain the over pressure condition.

摘要： The invention sets forth a hydraulic accumulator-damper which facilitates design and assembly of a brake system with a traction control for a motor vehicle. To this end, an end wall of a piston in a housing of the hydraulic accumulator is provided with a damping diaphragm. Between the damping diaphragm and the housing end wall, the damping diaphragm encloses a damping chamber into which a throttle bore discharges through the housing end wall.

摘要： A pulsation damper and noise attenuator assembly comprising a housing having an inlet port and an outlet port fluidly connecting the interior of the housing to the flow path of the fluid flow system. A base is mounted to the housing and comprises a vent fluidly connecting the interior of the housing to an external fluid source. A sealing member such as an expandable bellows or piston is seated within the housing and creates a fluid tight seal between the fluid flow path and the external fluid source sealing member. The external fluid biases the sealing member in a forward direction. The sealing member acting against the N.sub.2 fluid under pressure absorbs the full force of the hydraulic shock waves or pulsation within a high pressure fluid flow system as the assembly is mounted directly within the flow path of the fluid. The shock wave is exposed across the full face of the sealing member and dampened prior to the fluid continuing along the flow path.
