Abstract: A solenoid valve has a body with a fluid passage extending longitudinally at least partially through the body. Each of supply, control, and exhaust ports is disposed through the body and operably connected to the passage (the supply port also introducing fluid medium from a pressure source). Among the ports, there is a valve member operably disposed in the passage. A bore extends at least partially through the member. A metering orifice connects the passage or exhaust port with the bore. A solenoid portion has a coil with an armature movable within the portion in response to energization of the coil, and a shaft is connected to the armature. The shaft extends partially into the body and directly contacts the member, and the energization of the coil causes the shaft to slide within the solenoid portion and move the member in response to movement of the armature within the portion.

Abstract: The present invention is directed to a solenoid valve having a valve body with a fluid passage extending at least partially through the valve body. A supply port is disposed through the valve body and is operably connected to the fluid passage. The supply port introduces fluid medium from, such as hydraulic fluid, transmission fluid or some other suitable fluid from a pressure source such as a pump. A control port is also disposed through the valve body and is operably connected to the fluid passage. An exhaust port is also disposed through the valve body and is operably connected to the fluid passage. Between the control port and the supply port and the exhaust port there is a valve member that is operably disposed in the fluid passage. This is accomplished by way of a bore extending at least partially through the valve member. A metering orifice connects the fluid passage or exhaust port with the bore of the valve member.

Abstract: The present invention is an integrated two-stage low-leak control valve which is used to control pressure or flow in a hydraulic system such as an automatic transmission valve body. The control valve formed of a single assembly. A valve portion and a solenoid portion are located in the single assembly. The solenoid portion is operably connected to the valve portion with two variable orifices contained in the single assembly. A first variable orifice controls the flow of a fluid medium from a supply port in the integrated control valve to a pressure control region of the integrated control valve, and a second variable orifice controls the flow of the fluid medium to an exhaust port in the integrated control valve.

Abstract: A solenoid control valve for use in actuation of a manual hydraulic clutch in a vehicle. The solenoid control valve has an electronically operated solenoid with armature and actuator rod displaced through a channel in the solenoid. A spool valve has a valve body that is coupled at one end to the solenoid. A spool is slidably disposed in the control channel. A first and second dampener chambers are located at the two ends of the spool. The dampeners function to improve the stability in the control system and balance the transient flow forces of the hydraulic fluid as it moves through the valve member. The spool also has a control portion located between the first end and the second end of the spool. The control portion allows the control portion to communicate with a supply, control and exhaust passages in the valve body.
