摘要： A solenoid control valve (10) that includes an electromagnetic coil (30) positioned within a housing (16) and a spool valve (72) positioned within a central bore (70) of a valve body (20). An armature (40) is axially positioned within the coil (30) and an armature spring (52) biases the armature (40) against an opening in the central bore (70) when the coil (30) is not energized. The spool valve (72) includes an internal chamber and a pair of sealing lands (98,100) that selectively seal a supply port (92) and a control port (94) within the valve body (20). A pole piece (26), including an annular flux shunt portion (62), is threadably engaged with the housing (16) to control a working air gap (60) between the pole piece (26) and the armature (40). The flux shunt portion (62) more radially directs the electromagnetic field lines to weaken the magnetic force as the armature (40) moves closer to the pole piece (26). A deep drawn flux tube (64) is positioned within the housing (16), and the flux tube (64) and the housing (16) are attached to the valve body (20) by a crimped connection (22) at a common location.

摘要： A dual gain pressure control solenoid having two individually wound coils. One coil has a greater number of turns than the other coil and operates as a high force coil. The coil with a lesser number of turns operates as a low force coil. The low force coil provides improved resolution over a predetermine range of input current, while the high force coil provides less resolution but greater force. The coils may be used in various operational modes in order to achieve improved resolution over a predetermined current range.

摘要： A proportional variable bleed solenoid valve that includes magnetic force adjustments to provide magnetic calibration. The control valve includes a housing defining a chamber, where an electromagnetic coil is wound on a bobbin and is coaxially mounted within the housing. A movable armature is coaxially positioned within the bobbin in the chamber and has an armature poppet valve extending form a bottom end of the armature. An armature spring is in contact with an upper end of the armature and a top wall of the bobbin, where the spring positions the armature in an initial position when the coil is not energized and where the armature moves to a second position in conjunction with the bias of the armature spring when the coil is energized. A pole piece is mounted to the housing and is positioned adjacent to the lower end of the armature to define an air gap between the pole piece and the armature. The pole piece includes an extended annular ring positioned below the lower end of the armature such that the armature poppet valve extends through the ring. A mounting bracket is secured to the housing adjacent to the pole piece and a valve sleeve is connected to the mounting bracket. The valve sleeve includes a central bore axially aligned with the armature, where the central bore includes a widened portion proximate the armature poppet valve that defines a shoulder. A control ball is positioned within the widened portion and is positioned against a bottom seal surface of the armature poppet valve and a valve seat surface of the shoulder when the coil is energized to seal off an exhaust port, so that a supply pressure orifice connected to the valve sleeve provides a control pressure at a control pressure opening in the valve sleeve. In order to provide magnetic force adjustments for magnetic calibrations, the valve sleeve is selectively positionable relative to the bracket so that the distance between the armature poppet valve and the seat surface is adjustable. In one particular embodiment, the valve sleeve is secured to the bracket by a threaded connection so that its position can be readily changed.

摘要： 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.

摘要： A two-stage, variable force, solenoid control valve (10) for regulating fluid pressure can include a valve body (12) having a pilot fluid passage (14), including a metering land (16), in fluid communication with a flow amplifying fluid passage (18) through a valve control port (20) formed in the valve body (12). A solenoid operated pilot valve member (22), disposed in the pilot fluid passage (14), can have a metering orifice (24) operable in combination with the metering land (16) for selectively connecting the valve control port (20) with a pressurized fluid supply port (26) and a return exhaust port (28) in response to activation of a solenoid (34). A flow amplifying spool valve member (30), in fluid communication with the valve control port (20) of the pilot valve member (22) at one end (30a), can selectively connect a load control port (32) with the pressurized fluid supply port (26) and the return exhaust port (28) in response to pilot valve member (22) operation.

摘要： 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.
