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.
