Abstract: A direct drive servovalve (10) includes redundant drive motors (14) coupled to a common valve drive shaft (22,24) by a connection device (26). The connection device (26) is configured to allow operation of the servovalve (10) in the case where one or more of the drive motors (14) becomes inoperable, such as caused by jamming or binding of a rotor associated with the drive motor. By use of the connection device (26), in the event that one of the drive motors (14) was to become jammed, the remaining operable motors (14) can continue to stroke or cause translation of a valve member (18) of the direct drive servovalve (10) to allow its continued operation.

Abstract: A water supply valve comprising a valve body having a first orifice and a second orifice, a rotatable valve shaft, and a handle.

Abstract: A self-contained valve actuator of the present invention can comprise an actuator component. This actuator can be linear or quarter turn depending on the valve. The actuator can be double acting which means the piston will move once to open and once to close. The self-contained valve system uses hydraulic fluid to operate the valve. The valve system is directly powered with electric power from a battery. Solar panels are also incorporated to capture solar energy and convert this energy into electrical energy. This converted electrical energy is stored in the battery which enables the battery to continuously supply energy while substantially reducing the possibility of exhausting battery power. This resupply of electrical energy and the use of the hydraulic fluid creates a self-contained valve actuation system.

Abstract: In the braking systems of many vehicles, a parking brake is utilized that is spring applied and fluid pressure released. In the event of a mechanical breakdown, a mechanical device or other specialized tools must be used to bring about the disengagement of the parking brake so that the vehicle may be towed. The present invention overcomes this problem by providing an auxiliary actuating mechanism for a spring applied, fluid pressure released parking brake that includes an auxiliary accumulator that will maintain a preselected amount of pressure upon the loss of the primary source of pressure. An auxiliary actuating valve is positioned between the accumulator and the parking brake to selectively communicate fluid therebetween. The auxiliary actuating mechanism is provided with two remotely located actuators that may be utilized to selectively position the valve to permit the communication of the pressurized fluid within the accumulator with the parking brake assembly to achieve the disengagement thereof.

Abstract: An improved, remote controlled valve and dual push button assembly, having a hand operated push button which, when depressed and released, opens a water valve for a predetermined length of time after which the valve closes. The valve is also connected to a foot operated push button which, when depressed, holds the valve in an open configuration as long as the foot button is depressed. The improved valve and button assembly provides an air flow path through the foot button when the foot button is not depressed. The air flow path utilizes a hole in a diaphragm of the foot button which communicates with an air flow path in the base of the piston which depresses the foot button diaphragm. The disclosure also includes a check valve held in the needle valve which is a part of the timing mechanism of the hand operated button. The check valve prevents the flow of air out through the needle valve and permits air to only flow in through the needle valve.

Abstract: A peristaltic-type pump having an intake which may be conveniently connected to a liquid coating source includes an impeller having a pair of rollers. Rotation of the impeller causes the rollers to progressively compress a length of tubing in the pump. This compression creates suction to draw the coating material into the pump and pressure to drive a flow of coating to a handle attached to an applicator. The handle includes flow control devices which may be selectively operated to supply coating to the applicator only as required. During periods of non-flow the coating pressure is sensed to deactivate the pump when the pressure exceeds a preselected limit. Deactivation of the pump saves energy and prolongs a life of the pump.

Abstract: A tank car bottom unloading valve that meets A.A.R. specifications which can be dually-operated either from above or below the tank, wherein the valve is retained in a heavy, longitudinally sloped mounting flange by a segmented ring which does not interfere with the valve actuating mechanism and yet allows the containment of the valve up inside the tank so as not to result in hazardous protrusion of the body of the valve from the bottom of the tank. Said vale is shut from below by an over-center cam and link mechanism which locks the valve poppet on its seat through a resilient compression spring but which does not lock-up the valve when it is shut from above, so that lower working torque is required by the operator and less maximum stress is imposed on the valve in its operation, and there is less criticality of adjustment upon assembly. A valve actuating lever disengages from the over-center cam and link mechanism for rotation and hookup in an out-of-the-way place below the tank car.

Each of a pair of oppositely extending handles is pivotally mounted on a socket member secured to a key that rotates the valve, each handle being provided with a gear segment that meshes with a corresponding gear segment on the other handle whereby rocking of either handle about its pivot by a lever connected thereto effects rocking of the other handle so that a lug on one handle is moved to a position in which it will not engage a stop carried by the valve body upon subsequent arcuate movement of both handles while in their rocked position in response to a manual pull exerted on the lever connected to either one of the handles.

Abstract: A brake pipe end cock provided with a pair of operating handles disposed respectively on opposite sides of the end cock, whereby the end cock may be operated from either side of the car, because one handle, which is self-locking on one side, is connected by a crossover bar to the other handle on the opposite side, which may or may not be self-locking, as desired, to provide concurrent movement of the two handles as a unit, said crossover bar being necessary to unlock the self-locking handle in order to effect operation of the valve device if the non-locking handle is the one manipulated.
