Abstract: A regulator valve includes an inlet coupled for receiving a spray solution delivered by a fixed displacement pump coupled to a solution tank. Located in the valve body so as to divide the solution received at the inlet between a bypass or tank port of the regulator valve, and a boom port is a ball valve in the form of a hollow sphere having a first circular opening in register with said inlet, a second circular opening in register with said boom port and an elongate, wedge-shaped opening in register with said bypass port. The ball valve is mounted for rotation about an axis which is coaxial with the first circular opening and includes a stem coupled to an electric motor for actuating the valve, the motor being coupled for receiving a control signal for causing the motor to position the ball for dividing the flow so as to achieve a desired solution application rate.

Abstract: A 3/2 normally closed module includes a main body, a housing and a magnetically energizable coil. The main body includes a bore, an armature and a rod. The housing includes first and second valve seats and is configured to receive a first and second ball. The housing also includes a first, a second and a third port. When the module is in an energized state, current flows through the coil, generating a magnetic field. The magnetic field forces the armature against the rod, which in turn, forces the first ball to engage the first valve seat. As the first ball engages the first valve seat, the first ball forces the second ball to disengage from the second valve seat. As a result, a fluid flow path is created between the first and second ports. When the module is in a de-energized state, a spring, disposed between the main body and the second ball, forces the second ball to engage with the second valve seat.

Abstract: Method and apparatus for isolating hydraulic devices in a stacked hydraulic circuit of modular design employing an isolator valve module which enables partial and/or complete isolation of components in a hydraulic system to be isolated for inspection, testing, maintenance or replacement, by selective operation of the isolator valves in the isolator valve module.

Abstract: A multiport valve comprising a casing having at least one fluid inlet port and at least one fluid outlet port, a seal disposed adjacent to each outlet port, a cylinder disposed within a central opening in the casing and having an axial channel with a channel surface and at least one depression within the channel and balls biased toward the cylinder and away from each outlet port. Rotating the cylinder such that the depression aligns with the ball forces the biased ball into the depression and away from the seal opening the outlet port allowing for fluid flow therethrough and rotating the cylinder such that the depression is misaligned with respect to the depression causes the channel surface to overcome the bias and force the ball against the seal thus closing the outlet port. The multiport valve may include a bearing assembly disposed between the valve casing and cylinder and a ball biasing member angled to point towards the cylinder and bearing assembly, providing for ease in rotation of the cylinder.

Abstract: An anti-theft device is installed in a vehicle brake line which carries braking fluid. The device defines a valve seat and a valve body adapted to close against said valve seat, the valve body having a passageway therethrough and being rotatable against said seat about an axis substantially perpendicular to the passageway, between a first position in which it permits fluid flow in one direction and inhibits fluid flow in the opposite direction, and a second position in which it permits fluid flow in both directions. The valve can easily be switched between the first and second positions, and can be locked in the first position. By allowing braking fluid to flow only toward the wheels, it will be evident that the wheel brakes, once applied, cannot, be released.

Abstract: An isolator flow control apparatus (10) especially to selectively control communication of a contained fluid to an overpressure protection system. The isolator apparatus (10) includes a flow housing (12) having a single inlet opening (20) placed in fluid communication by an internal manifold means with a plurality of outlet openings (22, 24).

Abstract: A device for fluid mixing and flow control in showers, baths, and sinks. Three flow control valves are connected to a mixing chamber. Two of the valves control two inlet channels into the chamber, and the third valve controls the flow out of the chamber. The two inlet valves are linked to operate in unison in opposite phase (one opens when the other closes), providing a variable fluid mixing ratio. The complementary operation of these mixing valves causes their combined flow rate to remain constant while the mixing ratio varies. The third valve controls the total flow rate. This provides independent control of mixture and flow via a simple device. A circular dial can show the control arm positions clearly, allowing quick, absolute adjustment.

Abstract: An apparatus for mixing and dispensing fluid components includes a mixing chamber for mixing reactive components prior to dispensing the components. The components are provided through separate valves to ducts in fluid communication with inlets to the mixing chamber. The valve actuator can be selectively positioned to prevent one of the valve from opening. The valves are ball valves which are actuated by a hydraulic actuator acting through a rack and gear system. The rack is cylindrical with a flat spot formed thereon for preventing rotation of an associated one of the gears as the actuator is moved.

Abstract: First and second outlet ports are connected to an inlet port. A first valve member selectively blocks and unblocks the first outlet port. A second valve member selectively blocks and unblocks the second outlet port. A first device urges the first valve member. A second device urges the second valve member. A movable member disposed between the first and second valve members allows a force of the first urging device to travel to the second valve member. The movable member can be driven by a solenoid winding. When the solenoid winding is deenergized, the first valve member is moved to its open position by the first urging device and the second valve member is moved against a force of the second urging device to its open position by the first urging device. When the solenoid winding is energized, the first valve member is moved against the force of the first urging device to its closed position by the movable member and the second valve member is moved to its closed position by the second urging device.
