摘要： A fluid pump assembly for pumping hydraulic fluid through a controlled brake system includes a housing defining a pumping chamber. The chamber communicates with a hydraulic fluid circuit that operates the controlled brake system. A piston plunger is disposed within the chamber with a shaft affixed to the plunger. An electric coil is affixed to a casing having the shaft inserted therethrough. The coil is coaxially aligned with the shaft. The coil generates a magnetic field through an armature affixed to a distal end of the shaft disposed outside the chamber when receiving electrical current. The magnetic field draws the armature towards the casing for pumping hydraulic fluid from the chamber.

摘要： The invention is a two-stage, two-poppet prime valve assembly for use in high pressure applications such as vehicle braking systems. The valve assembly has two valve seats and two plungers for allowing the valve assembly to open under high pressure while providing minimal internal flow restrictions to enhance cold temperature and low pressure operation. The two-stage, two poppet valve assembly contains two separate flow paths, one being high pressure, relatively low flow called a stage one, and the other being relatively low pressure, high flow called a stage two. In addition, the valve incorporates a reverse flow bypass feature that is capable of controlling flow at very high pressure and allowing reverse flow with a very low pressure drop.

摘要： A vehicle solenoid valve includes an inlet port circumscribed by a rounded cup-shaped valve seat and an outlet port. A two-piece poppet is installed within the valve and includes a non-magnetic poppet shaft connected to a frustum-shaped poppet head. The poppet head includes an integrally formed, rounded nose that is sized and shaped to engage the rounded cup-shaped valve seat. The poppet is movable between an open configuration, wherein the rounded nose is distanced from the valve seat, and a closed configuration, wherein the rounded nose engages the valve seat to block fluid communication through the valve.

摘要： A braking system includes a master cylinder that is operational to introduce a manually effected braking pressure in the braking system and includes a wheel brake that is responsive to the manually effected braking pressure. A modulator is interconnected in the braking system between the master cylinder and the wheel brake and includes a pump that has an inlet and an outlet wherein the inlet is in continuous open fluid communication with the wheel brake through a first fluid passageway. The first fluid passageway is free of any flow restrictive orifices and the first fluid passageway is not in fluid communication with an accumulator. The modulator also includes a normally open valve that is positioned in a second fluid passageway and the second fluid passageway extends between the wheel brake and both the pump outlet and the master cylinder. During base brake operation of the braking system, the pump and the valve remain unoperated so that the manually effected pressure is freely transmitted to the wheel brake. During ABS release operation, the pump is turned on and the valve is energized to close, blocking the second fluid passageway so that a reduced wheel brake fluid pressure is effected at the wheel brake and a rate of reduction of the wheel brake pressure is established that is directly proportional to, and from a mechanical effect standpoint, is a result solely of pump flow rate.
摘要翻译：制动系统包括主缸，其可操作以在制动系统中引入手动制动的制动压力，并且包括响应于手动制动的制动压力的车轮制动器。调制器在主缸和车轮制动器之间的制动系统中相互连接，并且包括具有入口和出口的泵，其中入口通过第一流体通道与车轮制动器连续打开流体连通。第一流体通道没有任何流动限制孔，并且第一流体通道不与蓄能器流体连通。调节器还包括一个常开阀，其定位在第二流体通道中，第二流体通道在车轮制动器与泵出口和主缸之间延伸。在制动系统的基础制动操作期间，泵和阀保持未操作，使得手动施加的压力自由地传递到车轮制动器。在ABS释放操作期间，泵被打开并且阀被通电以关闭，阻塞第二流体通道，使得在车轮制动器处实现减小的车轮制动液压力，并且确定车轮制动器压力的降低率，与机械效果的观点直接成正比，仅仅是泵流量的结果。

摘要： An integral power booster and master cylinder assembly interactively operates with a braking system to effect conventional braking operation, anti-lock brake operation, traction control operation and stability enhancement system functions in a cost effective manner. The incorporation of a low pressure hydraulic booster provides a manner of enhancing first cycle response times of the traction control and stability enhancement system functions. Fluid separation is maintained between the stability enhancement system and the braking channels through the use of a pump priming accumulator to provide a pre-charge to the wheel brake pressure effecting pump assembly, in direct response to the power booster.

摘要： A pump and a pump piston assembly. The pump piston assembly includes a pump piston, a pump check valve, and a spring. The pump piston has a piston bore extending from a first piston end toward a second piston end. The pump check valve is positioned proximate the first piston end. The spring has an attached portion attached to the pump piston proximate the first piston end and has a biasing portion biasing the pump check valve to fluidly block the piston bore. The attached portion of the spring is closer to the second piston end than is the biasing portion of the sprint. The pump includes the pump piston assembly and a pump sleeve, wherein the pump piston is slidably engaged in the sleeve bore of the pump sleeve.

摘要： Cold temperature performance of a pump for a controlled braking systems is enhanced, and internal flow restrictions of the pump are minimized, by placing the poppet return spring in a separate cavity out of the flow path through the pump. The separate spring cavity also allows travel of the poppet to be limited, thereby also limiting the loss of volumetric efficiency due to flow forces generated by cold, viscous fluid pushing the poppet an increasing distance from the seating area.

摘要： A braking system generally provides pressure equalization between the sides of a split braking circuit. The amount of equalization provided is limited to enable the introduction of purposely induced pressure variances. A result is that unintentional pressure variations are moderated and intentional target pressure variations are easily obtainable. The braking system provides power braking operation in response to a manually actuated master cylinder. Fluid pressure is transmitted through isolation valves directly to the wheel brakes. The braking system also provides power operation in response to a powered pump. The pump delivers pressurized fluid through a controllable supply valve. When the supply valve is open, the isolation valve(s) are shifted to provide open fluid communication path between proportional pressure control valves and the wheel brakes. The pressure equalization effecting device is isolated from the master cylinder pressurized circuit during base brake operation.
