Abstract: A valve assembly having a plurality of fill valves that permit a fluid to flow from a fluid inlet into an interior flow path to increase a pressure of the fluid output from a fluid outlet, and a plurality of dump valves that permit the fluid to flow from the interior flow path to an exhaust to reduce the pressure of the fluid output from the fluid outlet. The valve assembly includes a controller that is configured for receipt of a command signal including a desired pressure of the fluid to be output from the fluid outlet, and is configured for receipt of a signal from a pressure sensor that is indicative of an actual pressure of the fluid output from the fluid outlet, wherein based on a comparison of the command signal with the signal indicative of the actual pressure, the controller is configured to selectively open and close each of the fill valves and each of the dump valves until the actual pressure is equal to the desired pressure.

Abstract: A solenoid pump that includes a base and a solenoid having a coil and a pole piece. A retainer body, positioned inside the solenoid and the base, includes an armature cavity that receives an armature in a sliding fit for movement between energized and de-energized positions. A diaphragm, mounted in the armature cavity, is connected to the armature. An inlet check valve permits fluid flow in only a first direction moving from an inlet port toward the diaphragm. An outlet check valve permits fluid flow in only a second direction moving from the diaphragm toward an outlet port. A fluid flow path extends through the retainer body from the inlet check valve to the diaphragm and from the diaphragm to the outlet check valve for transporting fluid from the inlet check valve to the outlet check valve as the diaphragm oscillates between first and second positions.

Abstract: A flow control valve including a valve body, stepper motor, and valve member. The valve member includes a poppet that can slide longitudinally within a bore of the valve body when the stepper motor receives electricity. A diaphragm, extending inwardly from the valve body to the valve member, deflects in response to movement of the valve member. A flow control needle, mounted to the poppet of the valve member, is at least partially received in an outlet port of the valve body. The flow control needle cooperates with an inner surface of the outlet port to define an outlet flow orifice that varies in size when the valve member moves between open and closed positions. In the closed position, a seat engagement surface of the valve member contacts a valve seat of the valve body to create a fluid-tight seal.

Abstract: A control valve having a valve body, seat member, valve member, and solenoid including a housing, bobbin, and coil. The valve member has a head portion disposed within the bobbin and a valve portion, disposed within the valve body, that has a seat engagement member operating to open and close ports in the valve body when the valve member slides between first and second positions. A permanent magnet, disposed within the bobbin, applies an attractive force of variable magnitude to the valve member in a direction opposing a biasing force created by a biasing component. Pulses of electric current applied to the coil change the variable magnitude. The permanent magnet pulls the valve member to the second position when the attractive force is greater than the biasing force and the valve member returns to the first position when the attractive force is less than the biasing force.

Abstract: A pulse valve assembly including a main valve and two pilot valves. The main valve includes a main valve body, main valve bore, and main valve spool. The main valve body includes an inlet port, an outlet port, and a pressure chamber at one end of the main valve bore. A first pilot valve selectively supplies pressurized fluid to the second pilot valve depending on the position of a poppet, which is controlled by a solenoid. A second pilot valve includes a spool that is driven by pressurized fluid from the first pilot valve. The second pilot valve selectively supplies pressurized fluid to the pressure chamber in the main valve causing the main valve spool to move towards the open or closed position. When the main valve spool is in the open position, pressurized fluid can flow through the main valve from the inlet port to the outlet port.
