摘要： A pulse free escalator system has two spaced apart pulse free turnaround sections and at least one pulse-free transition zone. A method of designing the turnaround sections and the at least one transition zone is described herein. The escalator system has a pair of guide tracks and a pair of linkage assemblies, each comprising a plurality of links joined together. Each linkage assembly has a plurality of rollers for supporting the linkage assembly which travel in a respective one of the guide tracks. Each guide track has two spaced apart turnaround portions with each turnaround portion defining a travel path for each roller having a linear entry section, a linear exit section, and a pulse-free section intermediate the two sections.

摘要： Magnetizing current generated in a linear induction motor driving elevator car doors in elevator systems is optimized. Magnetizing current level is set low for door operation modes requiring lower levels of thrust, such as hold open and hold closed. Magnetizing current level is increased for modes of door operation requiring greater thrust levels, such as closing or opening. Optimization of magnetizing current in linear induction motors reduces overheating and increases energy efficiency.

摘要： According to the invention, a valve for use with a variable speed motor and pump in an hydraulic elevator balances a fluid pressure force on a pump side of a control valve with a fluid pressure force on a cylinder side of the control valve before an elevator cab moves either upwardly or downwardly. On the pump side of the valve, a separate circuit, which is controlled by a solenoid, directs the pump fluid pressure force behind the valve until the sum of the fluid pressure acting on the pump side of the control valve overcomes the fluid pressure on the cylinder side of the control valve to open the valve.

摘要： A muffler for attenuating pulsations within the hydraulic fluid of an hydraulic elevator includes a plurality of compressible elements for absorbing pressure pulsations within the fluid and a baffle for ensuring that the flow of fluid contacts the elements sufficiently to absorb such pulsations, the baffle allowing a certain amount of flow to pass therethrough so that the pressure drop around the baffle is not so extreme so as to cause the muffler to cease to function.

摘要： The flow of hydraulic fluid to and from an hydraulic elevator piston is controlled by a motor-actuated spool valve operated by a microprocessor. To lower the elevator, a main check valve is opened by a down piston using hydraulic fluid from the system. Pressure is equalized on both sides of the main check valve just before the latter is opened thereby allowing the use of a smaller down piston using less hydraulic fluid. This results in smoother car motion during descent of the car. The addition of a solenoid valve bleed passage to equalize pressure on both sides of the check valve also prevents rapid descent of the elevator car in the event that the spool valve were to be open at the time descent commences.

摘要： A three-way solenoid valve uses a movable armature housed in a coaxial sleeve and having longitudinal fluid channels on its outer surface and a fluid sealing element on both ends. A first fluid sealing element on a first end of the armature is a resilient ring arranged to cooperate with an adjacent fluid orifice in a valve body to peripherally seal the fluid orifice in response to spring pressure exerted by a spring acting on the first end of the armature in a first position of the armature during an deenergized state of the valve. The armature is provided with a coaxial longitudinal bore aligned with the center hole in the fluid sealing ring. During the deenergized state of the valve, a fluid path is provided between a first fluid port and second fluid port in the valve body via the hole in the sealing ring, the bore in the armature and the channels on the armature. During an energized state of the valve, the armature is repositioned to a second position to effect a seal between the fluid sealing element on the second end of the armature and a fixed plug in the valve to interrupt the fluid path along the channels on the armature. In this state of the valve, the sealing ring is separated from the adjacent fluid orifice to provide a fluid path between the first fluid port and a third fluid port. A rolling diaphragm seal is arranged between the armature and the valve body to isolate the second port from the first and third ports.
