    摘要: A method for generating cavitation resistance in a liquid, a portion of which can be in contact with a surface is disclosed. The disclosed method can be carried out by pressure-treating the liquid, the liquid portion in contact with the surface, and/or the surface for a sufficient time to develop resistance to cavitation. The disclosed method can be carried out when the surface is made of a material having a surface roughness that is greater than the rc of the liquid. Suitable surfaces include borosilicate glass, drawn glass, copper, lead, steel, cast iron, metal alloys and concrete. The surfaces can be ship and boat propeller surfaces, the interior of fuel lines and fuel storage containers or any other surface where cavitation can occur.

    摘要: A void protection system includes a valve assembly, a second fluid source configured to provide hydraulic fluid to the hydraulic cylinder, an auxiliary valve configured to fluidly connect the hydraulic cylinder to the second fluid source, a sensor assembly, and a controller. The controller is configured to monitor fluid pressure within the hydraulic cylinder based on signals from the sensor assembly, based on a determination that pressure in a rod end or a head end of the hydraulic cylinder is below a first fluid pressure threshold, configure the valve assembly to fluidly connect the corresponding end to the first fluid source, and if the first fluid source is not operational, increase an opening of the auxiliary valve to fluidly connect the corresponding end to the second fluid source and cause the second fluid source to provide fluid until pressure in the corresponding end is above a second fluid pressure threshold.

    摘要: A diffuser assembly for a hydraulic reservoir is disclosed. The diffuser assembly includes an inlet tube for connection to the inlet to the reservoir. A middle portion of the middle tube is connected to a plurality of diffusers. The diffusers are disposed at an angle with respect to an axis of the inlet tube and the axis of the inlet to the reservoir so that fluid flowing into the reservoir must change flow directions for entering and exiting the diffusers. The disclosed diffuser assembly is less prone to damaged cause by fluid flow spikes and is particularly useful for high flow/high pressure applications.

    摘要: A controlling device for hydraulic consumers (10, 12) has one controlling valve (18) for controlling a supply pipeline (TReg) for the hydraulic consumer (10, 12) and a tank return pipeline (TRO). Because the control valve (18) is connected to an additional supply pipeline (TR) and constructed as a priority valve, the supply pipeline (TReg) receives priority preference of a fluid supply system over the priority of the tank return pipeline (TRO). A sensor circuit is realized which checks whether, in accordance with the load situation at the hydraulic consumer (10, 12), there is any need at all for a supply flow.

    摘要: In order to prevent a vehicle fitted with braking assistance and trajectory correction devices and having a highly placed center of gravity from overturning in a bend when there is a sudden turn of the steering wheel at the same time as a sudden braking action, a hydraulic braking circuit comprising a hydraulic pump (3) which sucks a fluid contained in a reservoir (3) through a master cylinder (1), is provided with a bladder (10). The bladder, placed between the master cylinder and the hydraulic pump, reduces the duration of flow of the hydraulic fluid to the pump, ensuring a sufficient suction pressure at the entrance of the pump in order to cram the brake and cause the wheel having the most pressure to skid.
