摘要： A current driving system for a solenoid valve is described herein. In an embodiment, the current driving system comprises a pre-driver to control a control input of a transistor coupled to an electrical input of a solenoid valve. The transistor inducts electric power into the solenoid valve when the transistor is switched on.The current driving system further comprises a signal generator to produce a small signal and to output the small signal to the electrical input of the solenoid valve. The electric power being supplied by the small signal into the solenoid valve is substantially smaller than the electric power being supplied by the transistor when the transistor is switched on. The current driving system further comprises a measurement unit to measure a response to the small signal at the electrical input of the solenoid valve.

摘要： A variable flow valve assembly is disclosed, and includes a main body, a piston, a position sensor, a controller, a solenoid, and a cover. The main body defines a chamber, an inlet port, an outlet port, and a wall located between the inlet port and the outlet port. The wall defines a metering orifice for selectively allowing a medium to flow from the inlet port to the outlet port. The chamber of the main body includes a pressurized chamber. The piston is moveable within the chamber of the main body in a plurality of partially open positions to vary the amount of medium flowing through the modulation orifice. The piston separates the pressurized chamber from the inlet port. The position sensor determines the position of the piston within the chamber of the main body, and the controller is in signal communication with the position sensor.

摘要： A pressure relief valve includes an outer frame, a ferromagnetic cylinder, a plastic air faucet, an electrical coil module and a spring. The plastic air faucet has a first end extending through a through hole of the outer frame and a second opposite end extending through a hollow channel of the ferromagnetic cylinder. The electrical coil module is located within the outer frame and has a central passage allowing the ferromagnetic cylinder to be accommodated inside. The ferromagnetic stopper is slidable along the central passage of the electrical coil module, wherein the ferromagnetic stopper has a seal gasket. The spring is located between the air faucet and the ferromagnetic stopper. When the electrical coil module is electrified, the ferromagnetic stopper and the ferromagnetic cylinder attract each other to against the resilient force of the spring to push the seal gasket against the air opening of the air faucet.

摘要： The present invention provides apparatus and methods for adjusting the atmosphere within a substantially sealed chamber containing respiring produce. The chamber of the present invention includes inlet means to permit ambient atmosphere to enter the chamber, and outlet means to permit chamber atmosphere to exit the chamber. Methods using apparatus of the present invention comprise: (a) monitoring the oxygen concentration within the chamber; (b) following detection that the oxygen concentration in the chamber has fallen below a predetermined amount, opening the inlet means so that the amount of oxygen in the chamber increases; and (c) removing carbon dioxide from the chamber atmosphere substantially at a predetermined rate, the predetermined rate having been selected such that the carbon dioxide concentration within the chamber atmosphere does not substantially exceed a predetermined amount. The methods may also comprise opening the inlet means for a time that is approximately proportional to the difference between the detected oxygen concentration and an oxygen setpoint.

摘要： A pilot-operated valve has a main poppet controlling fluid flow between inlet and outlet ports in response to pressure in a control chamber. Fluid flow through a pilot passage, linking the control chamber and the outlet port, moves an exhaust spool between first and second positions to control fluid flow through passages in the main poppet. The first position blocks flow between the control chamber and the outlet port and provides a path between the control chamber and the inlet port. In the second position, flow between the control chamber and the outlet port is enabled, and a second path, that is more restricted than the first path, is provided between the control chamber and the inlet port. When the valve closes, flow through the first path allows movement of the main poppet at a faster rate than during opening when flow occurs through the more restricted second path.

摘要： An electromagnetically actuated piston slide valve (1) with proportional characteristic comprises an axially movable piston (5) for closing radial passage openings (7). So as to change, with a cross-sectional area of the fluid passage openings (7) given by the magnetic drive, a parabolic course of the pressure loss at an increasing flow rate into a largely linear to degressive course, there is provided a pressure-sensing bore (9), which connects the fluid entrance side, at which pressure P1 is present, with the fluid exit side, at which pressure P2 is present. In the pressure-sensing bore (9) is axially displaceably disposed a pressure-sensing pin (10) and pushes, when pressure P1 is greater than pressure P2, the slide piston (5) into its open position. Thereby the free cross-sectional area of the fluid passage openings (7) increases, and the pressure loss ΔP=P1−P2 decreases correspondingly. By a suitable design of the ratio of the magnetic force applied by the magnetic drive and the pressure force applied by the pressure-sensing pin (10) the hydraulic characteristic curve (pressure loss against volume flow) can be adjusted.
摘要翻译：具有比例特性的电磁致动活塞滑阀（1）包括用于封闭径向通道开口（7）的可轴向移动的活塞（5）。为了改变由磁驱动器给出的流体通道开口（7）的横截面积，在增加的流速下的压力损失的抛物线过程成为大部分线性递减的过程，提供了压力（9），其将存在压力P1的流体入口侧与存在压力P2的流体出口侧连接。在压力感测孔（9）中，当压力P1大于压力P2时，滑动活塞（5）进入其打开位置时，压力传感销（10）轴向移动地设置。因此，流体通道开口（7）的自由横截面面积增加，并且压力损失ΔP= P1-P2相应减小。通过磁力驱动施加的磁力与由压力传感销（10）施加的压力的比率的适当设计可以调节液压特性曲线（体积流量的压力损失）。
