摘要： A method of processing a valve mechanism which includes a valve body having a shut-off surface in the form of a convex spherical surface, a valve hole, a valve seat formed by an opening of the valve hole, and a spring which urges the valve body toward the valve seat, wherein the valve mechanism is so formed that the valve body resists the urging force of the spring in accordance with the pressure increase in the valve hole to be separate from the valve seat, includes the steps of: preparing a processing tool having a processing surface in the form of a convex spherical surface which has the same curvature radius as the shut-off surface of the valve body; positioning the processing tool to the valve seat; and forming the valve seat along the form of the processing surface by pushing the processing surface of the processing tool against the valve seat.

摘要： A valve mechanism to control fluid flow between a fluid pumping device and a system that includes an inlet from the fluid pumping device, a first valve, a second valve, a first outlet fluidly connected to the system, and a second outlet. The first valve prevents backflow of fluid when the fluid pumping device discontinues pumping fluid to the system. The second valve checks fluid flow through the valve to the first outlet when fluid pressure at the inlet is less than a first predetermined pressure. The second valve permits fluid flow from the pump through the valve to the system only when fluid pressure at the inlet is greater than the first predetermined pressure. The second valve prevents fluid pressure in the system from substantially exceeding a second predetermined pressure when the pumping device is not pumping fluid to the system.

摘要： A diaphragm head with a high energy content of the oil space (pressure×volume) has a strong negative influence on the corresponding behavior of the oil overflow valve. The reaction of the valve leads to an undesirable increase in the opening time by which more oil is discharged than oil introduced by means of a compensation pump. This has the result that after multiple strokes the diaphragm is not driven to its dead position. With this, all of the compressed gas is not expelled which is accompanied by a rapid decrease of the suction capacity.The solution to this problem according to the present invention is achieved by means of a flow-interrupting edge formed at the junction of the valve seat and a restriction piece at the outlet side by which the operating forces of the valve spindle are sharply reduced. With this the effective closing force of the spring, as the dominant force component, leads to the desired fast closing time to the valve.
摘要翻译：具有高能量含油量的隔膜头（pressurexvolume）对油溢流阀的相应行为有很强的负面影响。与通过补偿泵引入的油相比，阀的反应导致打开时间的不期望的增加，通过该打开时间更多的油被排出。结果是在多次行程之后，隔膜不被驱动到其死位置。由此，所有的压缩气体都不会被排出，伴随着吸力的迅速降低。根据本发明的这个问题的解决方案是通过形成在阀的连接处的流动中断边缘阀座和出口侧的限制件，通过该限制件，阀主轴的操作力急剧减小。因此，作为主力分量的弹簧的有效闭合力导致对阀的期望的快速关闭时间。

摘要： A ported pressure relief valve (10) used in an automotive fuel system (F) includes an unrestricted constant bleed orifice (32) for routing pressurized fuel from a fuel pump (P) back to a fuel source (T, M) when an engine (E) is running. A check valve (30) prevents flow from a fuel system back to the fuel source when the engine is off, so to retain sufficient pressure in the delivery system that the engine will readily start when cranked. A pressure relief valve (50) drains fuel from the delivery system back to the source of fuel in response to a pressure build up in the fuel delivery system above a predetermined pressure level so to prevent an overpressure condition which would otherwise damage the fuel delivery system.

摘要： A flow reversal control valve for use in a fuel cell. The valve includes a housing having a first end and a second end disposed along a longitudinal axis. The valve also includes a wall that defines a first passage in fluid communication with a second passage. The first passage is disposed proximate to the first end and the second passage is disposed proximate to the second end. The valve further includes a chamber in fluid communication with the first and second passages. There are flow flutes formed in the chamber. A seal is disposed in the chamber and coupled to at least one of the first and second passages. The seal has an elastomeric member disposed on a planar surface transverse to the longitudinal axis. There is a closure member disposed in at least one of the first passage, second passage and the chamber. A resilient member acting on the closure member can operate to prevent fluid communication between the first and second passages in a first position where the closure member abuts the elastomeric member when the pressure of the fluid of one of the first and second passages is generally equal to a fluid pressure of the other one of the first and second passages. The resilient member and the closure member can also operate in a second position to permit fluid flow between the first and second passages when the fluid pressure of one of the first and second passages is not equal to the fluid pressure of the other of the first and second passages. The flutes maintain a laminar flow between the first and second passages and guide the closure member towards the seal when the closure member is in the second position.
