Abstract

Disclosed is a solenoid operated modular valve including a valve body, a valve member slidingly received in the valve body, and a solenoid that moves the valve member relative to the valve body along a longitudinal axis between an open position and a closed position. The valve body has an end face, a side face, and an inner bore. An outlet port in the end face is disposed in fluid communication with the inner bore. An inlet port in the side face is disposed in fluid communication with the inner bore. The valve body includes an O-ring valve seat that is positioned longitudinally between the inner bore and the outlet port. The valve member includes a tapered end that has a frustoconical shape and a valve member abutment surface. The valve member abutment surface contacts the O-ring valve seat when the valve member is in the closed position. The operational life of the elastomeric seal components is improved as the valve seat O-ring material does not need to be bonded with adhesive, so the O-ring material selection is able to be made on resisting corrosion.

Claims (8)

1. A solenoid operated modular valve, comprising: a valve body including an end face, a side face, an inner bore, an outlet port in the end face that is disposed in fluid communication with the inner bore, an inlet port in the side face that is disposed in fluid communication with the inner bore, and a connection end opposite the end face; a valve member slidingly received in the inner bore of the valve body, the valve member extending along a longitudinal axis; a solenoid including a solenoid body that is connected to the connection end of the valve body and a coil disposed inside the solenoid body that extends annularly about the longitudinal axis, the solenoid being operable to move the valve member relative to the valve body along the longitudinal axis between an open position and a closed position; and a biasing member positioned in the inner bore of the valve body that biases the valve member towards the open position, wherein the valve body includes an O-ring valve seat that is positioned longitudinally between the inner bore and the outlet port, and wherein the valve member includes a tapered end that has a frustoconical shaped valve member abutment surface that contacts the O-ring valve seat when the valve member is in the closed position and that is spaced away from the O-ring valve seat when the valve member is in the open position.
2. The solenoid operated modular valve of Claim 1, wherein the solenoid extends between a first end and a second end, wherein the valve body is connected to the first end of the solenoid, and wherein the solenoid includes a pole piece having a pole piece flange positioned longitudinally between the coil and the connection end of the valve body and a cylinder portion that extends from the pole piece flange into the coil from the first end of the solenoid, an end stop that extends into the coil from the second end of the solenoid, and an armature slidingly disposed in the coil between the cylinder portion of the pole piece and the end stop.
3. The solenoid operated modular valve of Claim 2, wherein the solenoid includes a bobbin supporting the coil, the coil extending annularly about the bobbin.
4. The solenoid operated modular valve of Claim 3, further comprising: a bushing including a bushing flange and a cylindrical portion that extends from the bushing flange, the bushing flange positioned longitudinally between the pole piece flange and the coil such that the bushing flange prevents longitudinal movement of the bushing relative to the coil, the cylindrical portion of the bushing being received in the bobbin and extending annularly about the cylinder portion of the pole piece, the armature, and at least part of the end stop; at least one pole piece seal that extends annularly about the cylinder portion of the pole piece and is positioned radially between the cylinder portion of the pole piece and the cylindrical portion of the bushing, the at least one pole piece seal creating a first static seal between the bushing and the pole piece; and at least one end stop seal that extends annularly about the end stop and is positioned radially between the end stop and the cylindrical portion of the bushing, the at least one end stop seal creating a second static seal between the bushing and the end stop.
5. The solenoid operated modular valve of Claim 4, wherein the pole piece includes a longitudinal bore extending therethrough, wherein the valve member includes a plunger portion adjacent to the tapered end, a stem portion that extends through the longitudinal bore of the pole piece and contacts the armature, and a piston portion, positioned longitudinally between the plunger portion and the stem portion, that is slidingly disposed in a slip fit with the inner bore of the valve body, and wherein the biasing member is positioned longitudinally between the piston portion of the valve member and a support surface disposed in the inner bore of the valve body adjacent to the valve body abutment surface.
6. The solenoid operated modular valve of Claim 5, wherein the first and second static seals provide a pressurized chamber within which the entire valve member and the entire armature are disposed, the pressurized chamber formed of the inner bore of the valve body, the longitudinal bore of the pole piece, and space inside the bushing between the cylinder portion of the pole piece and the end stop.
7. The solenoid operated modular valve of Claim 4, 5 or 6, wherein the bushing and the end stop are made of non-magnetic materials and the solenoid body and the pole piece are made of magnetic materials such that the solenoid body and the pole piece cooperate to concentrate magnetic flux inwardly towards the longitudinal axis.
8. The solenoid operated modular valve of any one of Claims 3 to 7, wherein the end stop is movably positioned in the bobbin and further includes a threaded end, threadably engaged with the solenoid body, that permits adjustment of a longitudinal position of the end stop and therefore a stroke length of the valve member by rotation of the end stop relative to the solenoid body.
