    摘要: Système et méthode de régulation de la pression dans le cylindre de frein (56) d'un frein de roue. Le cylindre hydraulique est connecté à une électropompe (12) et une valve de régulation de débit (50, 50', 100) est connectée entre la pompe et le cylindre de roue. Le système et la méthode permettent de régler la vitesse d'une électropompe de manière à générer la pression voulue dans un cylindre de frein; à générer une pression différentielle, dans la valve de régulation de débit, proportionnelle au débit de la pompe, et à communiquer celle-ci à un élément de valve soumis à l'action d'un ressort; à provoquer le mouvement de l'élément de valve, en réponse aux forces générées par la pression différentielle et agissant sur l'élément de valve, et à la force du ressort de compensation, de manière à ouvrir et fermer sélectivement un orifice de sortie associé, connecté à un drain ou à un réservoir, de telle manière que dans l'état stable, une condition d'équilibre est atteinte dans laquelle les forces de pression sont égales à la force du ressort et la pression dans le cylindre hydraulique est constante.

    摘要: A compressor drive system for controlling the gas pressure in a pressure gas volume (106) connected to the compressor (101). A brushless alternating current motor (23) is directly coupled to the compressor, which is driven with the same speed as the motor. The pressure in the gas volume (106) is sensed by pressure sensing means (109) connected to a converter (114). The converter simultaneously changes the amplitude and frequency of the drive voltage supplied to the motor (23). This is done in response to pressure changes in volume (106). The motor is stopped if the pressure exceeds a preset maximum value. A pressure gas container (104) is depressurized at motor stop to allow restarting without counter pressure on the compressor. Means (44) for controlling the amplitude and frequency of the drive voltage is provided so that the normal speed maximum load current is never exceeded during motor start.

    摘要: The present invention is a fluid distribution system comprising connected conduits (e.g., lines) wherein fluid flows, such as pipes within a building. The lines may be configured to: (i) include multiple lines that connect at intersections (some of the intersections will be identified as nodes); and (ii) incorporate node units associated with line pressure loss simulation assemblies ("LLSAs"). Activities of a node unit incorporating a LLSA can result in alterations in fluid pressure, such as by a loop control process to reposition balancing valves or other valves of one or more LLSAs, and/or by alteration of the speed of the system pump. These activities adjust fluid pressure to cause the system to produce a balanced and high efficiency energy transfer (e.g., heating or cooling), and do not involve or require any identification or use of any specific, fixed or absolute pressure value. They function based on an operation locus (for a node unit) and/or an operation locus range (for node unit groupings) to adjust the fluid pressure.

    摘要: A system includes a fluid controller coupled to an inflatable bladder and configured to add fluid to and remove fluid from the inflatable bladder, a control unit (2840) configured to provide information used by the fluid controller to adjust the pressurization of the inflatable bladder, the control unit including a user interface configured to constantly display a plurality of indicia corresponding to a range of pressure levels in which the inflatable bladder is employed by a user, where each of the plurality of indicia is associated with a different level of pressure of the inflatable bladder, respectively. In one embodiment, the fluid controller is configured to adjust the pressurization, in response to a user input at the user interface, to a pressure level selected by the user based on a current pressure level of the inflatable bladder, the pressure level selected by the user and an operating time of the fluid controller. In a further embodiment, a first indicia included in the plurality of indicia is associated with the current pressure level and a second indicia included in the plurality of indicia is associated with the pressure level selected by the user.
