    Abstract: A check valve assembly includes a housing extending axially along a center axis of the check valve assembly from a first end to a second end. The housing can include an opening disposed at the first end and an outlet disposed at the second end. A seat is disposed in the opening and connected to the tubular housing. The seat includes an inlet extending axially through the seat. A ball is disposed inside the tubular housing and disposed axially between the seat and the outlet. The ball is larger in diameter than the inlet. A ball guide is disposed inside the tubular housing and is disposed axially between the ball and the outlet. A spring is disposed inside the tubular housing and disposed axially between the ball guide and the outlet. The spring is compressed between the ball guide and the outlet.

    Abstract: A fluid cover for a displacement pump includes an inlet and an outlet oriented to provide desired flow characteristics to fluid entering a fluid chamber defined between the fluid cover and a diaphragm. The inlet is positioned to provide fluid to the fluid chamber at an oblique angle relative to the fluid cover. The oblique angle prevents the fluid from impinging on the fluid cover and the diaphragm, thereby maintaining a fluid velocity within the fluid chamber. The fluid velocity and rotational movement of the fluid facilitates flushing of the fluid chamber, as areas of low velocity or no velocity are eliminated from the fluid chamber, thereby preventing residuals from settling within the fluid chamber. The outlet is also positioned at an oblique angle to the fluid cover to maintain the rotational movement of the fluid flow.

    Abstract: A positive displacement pump includes a housing surrounding a drive chamber and a diaphragm compartment. A drive element is inside the drive chamber. A diaphragm is inside the diaphragm compartment and divides the diaphragm compartment into a fluid chamber and a cavity. A shaft connects the drive element and the diaphragm. A breather valve is fluidically connected to the cavity and is configured to allow air to exit the cavity. The cavity is fluidically disconnected from the drive chamber.

    Abstract: An air operated pump 10 uses a magnet 14 mounted in the valve cup 16 of the air motor 18 and two reed sensors 20 mounted in the valve cover 22 to monitor the speed and position of the valve 16. A solenoid 24 is mounted on the valve cover 22 and can be commanded to extend a plunger 26 into the valve cup 16 to stop valve movement and therefore the pump from running away A magnetoresistive sensor 34 is located in the center of the air motor 18 to precisely monitor the piston 36 position and with air valve sensors 20 provides the input necessary for precise control and diagnostics of the pump 10 and makes it suitable for metering and plural component application.
