Abstract: A controlled brake solenoid valve assembly includes a housing defining a channel. An actuating member including an armature and a plunger slidably disposed in the channel. A head portion extends outwardly from the plunger to a distal end. A drawn seat includes a narrowed portion disposed in the channel and defines a first compartment, a shoulder, and a hole. An elastic member disposed in the channel to bias the actuating member away from the drawn seat to define an opened position. The actuating member includes an actuator for moving the plunger from the opened position to a closed position. The distal end includes a restricting member, disposed in the hole, extending outwardly from the distal end, spaced from the terminal end, for providing annular fluid flow. A restricting block defines a restricting orifice having a variable diameter disposed in the first compartment to provide an orifice fluid flow.

Abstract: An electromagnetic valve assembly including a magnetic core defining a channel. A valve seat is received by the channel and defines a compartment. An outflow chamber is defined between the magnetic core and the valve seat. The valve seat defines an orifice that fluidly connects the compartment of the valve seat and the outflow chamber. A tappet is axially moveable to open and close the orifice. The valve seat further defines a check valve orifice fluidly connecting the compartment of the valve seat and the outflow chamber. A ball overlies the check valve orifice. A filter seat is secured to said valve seat. A ball guide is disposed in alignment with the check valve orifice and defines a guide passage that receives the ball for guiding the ball toward and away from said check valve orifice. The guide passage is defined by the valve seat and the filter seat.

Abstract: An actuator system including a receiving body defining a mounting bore, a inlet fluid channel, an outlet fluid channel and a connecting channel between the inlet fluid channel and the outlet fluid channel, a valve seat disposed within the connecting channel, and an actuator assembly connected to the receiving body, the actuator assembly including a sealing tip extending into the mounting bore, the sealing tip being adapted to sealingly engage the valve seat.

Abstract: Valve and method for a brake control actuator are provided. The valve includes a rod operable between respective operating conditions to selectively allow passage of brake fluid through the valve. The valve further includes a ball affixed at one end of the rod. The ball includes a sealing section that, upon engagement against a ball-receiving seat in the valve, blocks passage to brake fluid therethrough. The ball further includes a mounting section integral with the sealing section. The mounting section is configured to provide a reduced footprint relative to a spheroidal footprint and enable a strong mechanical joint between the mounting section and the rod.
