摘要： A change-over valve comprises a spool housed in a spool housing, and a pilot chamber facing at least an end of the spool. An axial passage is formed in the spool along the axial direction. While being connected to a pilot chamber, the axial passage communicates with a tank passage via a small hole having an opening on an outer periphery of the spool in accordance with displacement of the spool, to discharge the air in the pilot chamber to the tank passage. Since the axial passage is formed at a location offset from a center axis of the spool, a length of the small hole is shortened and the small hole is easily processed.

摘要： A method of testing a pressurized liquid fluid for dissolved gasses includes evacuating both a first tank and a second tank. A test volume of a pressurized liquid fluid is introduced into the first tank. An initial absolute pressure in the second tank is sensed, and then fluid communication between the first tank and the second tank is opened to allow the pressurized fluid to flow from the first tank into the second tank, thereby de-pressurizing the fluid. The de-pressurized fluid in the second tank is maintained for a pre-defined out-gassing period, to allow any gasses in the de-pressurized fluid to separate from the de-pressurized fluid. A final absolute pressure in the second tank is sensed. A difference between the final absolute pressure and the initial absolute pressure is correlated to a volume of gasses released from the de-pressurized fluid.

摘要： An in-tank filter bowl de-aeration shroud for a hydraulic or oil reservoir includes an outlet shroud surrounding the filter bowl outlet at a proximal end thereof and having a shroud fluid outlet at a distal end thereof with a larger opening than an opening of the filter bowl outlet. The outlet shroud may be formed as or include a diverging member surrounding the filter bowl outlet at a proximal end thereof and having a diverging member fluid outlet at a distal end thereof, wherein the member diverges from the proximal end to the distal end thereof. The outlet shroud may further include a central deflector positioned within the diverging member and combining with the diverging member to form an annular passage to the diverging member fluid outlet.

摘要： A wave power generation system includes a power generation component and a hydraulic component. The hydraulic component includes a cylinder and a piston. The cylinder connects to the power generation component. The cylinder has an accommodation space and a vent located in the middle section of the accommodation space such that the vent runs outside from the accommodation space. The accommodation space is used for accommodating a fluid. The piston is disposed in the accommodation space and is used for being guided by the accommodation space and sliding relative to the cylinder. Thereby, this drives the power generation component to convert mechanical energy into electrical energy, and to force the remaining air in the accommodation space and remaining air in the fluid to be discharged via the vent.

摘要： Generally, example systems and methods for measuring aeration level of a liquid may involve measuring the pressure at two points in the liquid reservoir. The aeration level of the liquid in the liquid reservoir may be calculated based on the pressure differential between the two points in the liquid reservoir. Optionally, the aeration level of the liquid may be compared to a threshold value of the liquid aeration level, and a machine action may be commanded if the aeration level exceeds the threshold value. Example machine actions may include warning the operator. In addition, data relating to the level of aeration of the liquid may be stored, along with other machine parameters, and the data correlated for analysis and machine diagnostics.

摘要： A fluid storage tank including an entrained air removal mechanism is provided. The entrained air removal mechanism assists in consolidating small air bubbles entrained within the fluid into larger bubbles such that the air bubbles have sufficient buoyancy to escape the fluid flow. The entrained air removal mechanism may be in the form of a plurality of saw toothed slots communicating different chambers within the fluid storage tank. The fluid storage tank can also be configured to direct fluid flow towards the sidewalls of the fluid storage tank as the fluid transitions from one chamber to another to promote heat transfer out of the fluid storage tank and to avoid the fluid within the tank acting as a thermal insulator.
