A fuel pressure accumulator for a fuel supply circuit of a turbine engine having at least one pipe is provided. The fuel pressure accumulator generally includes at least one housing adjacent to said pipe and receiving at least one deformable enclosure confining a gas and having at least one movable wall in contact with the fuel in order to dampen a fuel overpressure, where the housing is coaxial with the pipe and the accumulator has a permeable chamber delimited at least partially by the housing, pressurizing the deformable enclosure and communicating with the main fuel flow via a grid with staged walls tilted, with respect to a direction of the flow flowing along the grid, substantially in the direction of the deformable enclosure.

A snubber includes a head portion, a shank portion, and a threaded portion. The shank portion is attached to the head portion, and the shank portion defines a shank diameter. The threaded portion is attached to the shank portion, and the threaded portion includes an external helical thread wrapped around a central shaft. The external helical thread defines a threaded diameter, and the central shaft defines a central shaft diameter. The shank diameter and the thread diameter are sized such that the shank portion and the threaded portion define at least one fluid flow path when the snubber is installed in a pressure sensor.

A pressure reducing valve may include a valve body, a connecting tube, and a pressure-reducing member. The valve body is a three-way intercommunicated valve body which respectively forms into a water inlet end, a water outlet end, and a pressure-reducing tube. The connecting tube is connected to an extending section thereof, and at least a first annular groove is formed at an outer periphery of the extending section for disposing an O-ring thereon. An annular surface formed between the connecting tube and the extending section is faced to the extending section. The pressure-reducing member is hollow and has a closed end and an open end, and a buffer block is installed therein. The open end is abutted against the annular surface of the extending section, and a coupled portion between the open end and the annular surface is welded together to form a welding portion therebetween.

A water hammer prevention system using an operation state analysis algorithm to prevents water hammer. Data is measured in real time by a pressure sensor and a water level sensor are transmitted to a control unit and stored in a database. The control unit includes an air chamber which controls the operations of an air compressor and an air exhauster to prevent water hammer. The control unit performs calculations according to a water hammer algorithm, and determines the operation states of the air compressor and the air exhauster, and whether the water hammer prevention equipment is operating normally. Active operational control of the water hammer prevention equipment can be performed by applying a data analysis technique thereto, and a failure or operation error can be identified.

A heat exchanger for a vehicle is disposed in a fluid circuit in which a fluid is circulated according to an operating condition of the vehicle. The heat exchanger includes a tank and a pressure adjuster. The tank defines a tank chamber therein and is configured to allow the fluid to flow through the tank chamber. The pressure adjuster is disposed inside the tank and defines a damper chamber separately from the tank chamber. The pressure adjuster is configured to be displaceable or deformable to expand and reduce the damper chamber. The damper chamber is filled with a compressible gas. The pressure adjuster is configured to reduce the damper chamber in response to an increase in a pressure of the fluid in the tank chamber. The pressure adjuster is configured to expand the damper chamber in response to a decrease in a pressure of the fluid in the tank chamber.

A silencer includes a main body provided with a flow path having inlet and outlet ports of steam, configured such that the outlet port is submerged in drain, and including a submerged portion configured such that the steam contacts, in the flow path, the present drain having flowed in through the outlet port, and a porous member covering the outlet port.

A water hammer mitigation system includes a branch connection with ends coupled to a main pipeline, where a first end connects at a surge point on the main pipeline and a second end fluidly connects to the main pipeline at a distal point. A bi-directional surge relief device is disposed on the branch connection, and is operable to move to a first open configuration to permit pipeline fluid within the main pipeline to flow through the branch connection when surge point pressure reaches a designated pressure. The device can also move to a second open configuration when surge point pressure reaches another designated pressure. The device is closeable when surge point pressure is between the designated pressures.
