Abstract: A method of pressurizing a closed-cycle engine includes performing a non-steady state operation in which a working fluid flows to or from a pressurized tank: i) to or from a plurality of sumps defined by respective ones of a plurality of cylinder-piston assemblies of the closed-cycle engine; or ii) to or from one or more air bearings associated with each one of the plurality of the cylinder-piston assemblies; or iii) both and performing, before and/or after performing the non-steady state operation, a steady-state operation in which the working fluid flows through the plurality of sumps and the one or more air bearings along a steady-state loop that is fluidly decoupled from the pressurized tank.

Abstract: A hydraulic brake arrangement for a bicycle with a transmitting unit with a brake lever, and a cylinder housing with a cylinder space, and with a piston unit displaceably received in the cylinder space. In the tank space of an equalizing reservoir device, a membrane unit is disposed which subdivides the tank space into a fluid space for the hydraulic fluid and an air space sealed against the fluid space. The air space is connected with atmosphere through a vent opening. When the membrane unit is mounted, a filling mouth is in fluid connection with the fluid space. The vent opening opens into a receiving space that is at least partially enclosed by the base body of the transmitting unit. In the receiving space, an actuating mechanism is disposed which transmits force from the brake lever to the piston unit.

Abstract: A hydraulic actuator control system performs pressure compensation in the system by monitoring the pressure differential across a meter-out device. A flow of fluid can be directed from a pump through a meter-in device to a chamber of an actuator via a first port. In response to the flow of fluid entering the first port of the actuator, a return flow of fluid can be directed from a second port of the actuator through the meter-out device to a tank. The meter-in device can monitor a pressure differential across the meter-out device. The meter-in device can control the flow of the fluid from the pump to the actuator to place the pressure differential across the meter-out device within a desired range.

Abstract: A remote hydraulic system for an aircraft may provide hydraulic fluid to nose landing gear while being isolated from the main landing gear and other main hydraulic systems of the aircraft. A supply pressure accumulator may be configured to supply hydraulic fluid to a hydraulic load of the nose gear. A pressure sensor may be configured to detect a hydraulic pressure in the supply pressure accumulator. A pump may be in fluid communication with the supply pressure accumulator and configured to switch on in response to the hydraulic pressure below a threshold value. A return pressure accumulator may be configured to store the hydraulic fluid returning from the hydraulic load. The pump may drive fluid from the return pressure accumulator to the supply pressure accumulator.

Abstract: A four-state adjustable air path structure is an air storage-type pneumatic actuating mechanism. An air source (1) is respectively connected to an air storage tank (3) and a port a1 of a two-position three-way solenoid valve A (4) via a check valve (2). A port c1 and a port b1 of the two-position three-way solenoid valve A (4) are respectively connected to a port c2 of a two-position three-way solenoid valve B (6) and a vent hole (5). A port a2 and a port b2 of the two-position three-way solenoid valve B (6) are respectively connected to a port b3 of a two-position three-way solenoid valve C (8) and a port of a throttle valve (7). Another port of the throttle valve (7) is connected to a port a3 of the two-position three-way solenoid valve C (8). A port c3 of the two-position three-way solenoid valve C (8) is connected to an air tank (9). The present air storage-type pneumatic actuating mechanism uses air as a medium, utilizing the compressibility of the air to achieve a centralized air supply, thereby significantly simplifying processing and maintenance of a mechanical structure. Intellectual control of an operating speed can also be achieved. The present invention has advantages such as structural simplicity, low manufacturing costs, safe and reliable operation, long service life, and suitability for long-distance transmission.
