Abstract
A two-position, three-way solenoid-actuated valve includes a valve assembly having an axial opening and a valve member fixed in the axial opening with a first valve seat and a second valve seat disposed in the axial opening. The valve assembly including a ball disposed in the axial opening and moveable between the first valve seat and the second valve seat. The two-position, three-way solenoid-actuated valve also includes an electromagnetic coil assembly engaging the valve assembly to move the ball between the first valve seat and the second valve seat to open and close a fluid path through the valve assembly to provide directional flow control.
Claims23
A two-position, three-way solenoid valve comprising:
- a valve assembly having an axial opening and including a valve member fixed in said axial opening having a first valve seat and a second valve seat disposed in said axial opening;
- said valve assembly including a ball disposed in said axial opening and moveable between said first valve seat and said second valve seat;
- an electromagnetic coil assembly engaging said valve assembly to move said ball between said first valve seat and said second valve seat to open and close a fluid path through said valve assembly to provide directional flow control;
- and
- a blow-off assembly disposed in the axial opening and including a blow-off rod, a case extending axially from said rod and having an aperture in one end, a second ball moveably disposed in the case, and a first spring forcing the second ball toward the aperture.
A two-position, three-way solenoid-actuated valve comprising:
- a valve assembly having an axial opening;
- said valve assembly including a housing assembly extending axially having said axial opening and a valve member disposed and fixed within said axial opening and having a first valve seat;
- said housing assembly including means forming a second valve seat within said axial opening;
- said housing assembly including a ball disposed in said axial opening between said first valve seat and said second valve seat;
- said valve assembly including a blow-off valve assembly disposed and moveable in said axial opening to move said ball between said first valve seat and said second valve seat, said blow-off valve assembly including a blow-off rod, a case extending axially from said rod and having an aperture in one end, a second ball moveably disposed in the case, and a first spring forcing the second ball toward the aperture;
- said valve assembly including an armature assembly cooperating with said blow-off assembly;
- and
- an electromagnetic coil assembly engaging said valve assembly and moving said armature assembly in response to energization.
