Abstract: The present invention discloses operation of a system for injecting a predetermined amount of a secondary fluid into a primary fluid stream. The system uses a liquid additive injection pump driven by a fluid powered motor that is driven by the primary fluid stream and can be selectively suspended by an automated switch mechanism. The automated switch mechanism comprises an actuator in communication with an actuating shaft and a fluid source. When the actuator is pressurized, an actuating shaft is displaced relative to a housing which either engages or suspends the fluid-powered motor.

Abstract: A liquid additive injection pump for injecting a predetermined amount of a secondary fluid into a primary fluid stream wherein a fluid mixing chamber is disposed within the pump housing assembly. A gasket having at least one one-way valve is positioned between the pump assembly components and mixing chamber thereby allowing a primary fluid to pass through the pump assembly and into the mixing chamber where the introduction of a second fluid occurs. The mixed fluids are then discharged through an outlet. The one-way valve gasket assembly acts to prevent the mixed and/or secondary fluid from passing upstream of the gasket assembly and into the pump assembly.

Abstract: A particulate trap regeneration system is provided, which may include a particulate trap having a filter medium configured to remove one or more types of particulate matter from an exhaust flow of an engine and a regeneration device configured to reduce an amount of particulate matter in the particulate trap, as well as a radio frequency-based particulate loading monitoring system configured to determine an amount of particulate matter trapped by the filter medium. The particulate loading monitoring system may include at least one radio frequency transmitting probe configured to transmit radio frequency signals of predetermined magnitude and predetermined frequency toward the filter medium and at least one radio frequency receiving probe configured to receive and measure the magnitude of received radio frequency signals that pass through the filter medium.

Abstract: A system for injecting a predetermined amount of a secondary fluid into a primary fluid stream uses a liquid additive injection pump driven by a fluid powered motor driven by the primary fluid stream. The liquid additive pump has a reciprocating piston movable within a cylinder between upstroke and downstroke positions to meter the secondary fluid and a piston sealing mechanism comprising spaced-apart distal and proximal sealing elements. The distal piston-sealing element is flared in the direction of piston downstroke and the proximal piston-sealing element is flared in the direction of piston upstroke.

Abstract: An inline backwash, flushing filter assembly comprising a header assembly, a rotatable valve assembly, and a filter element assembly disposed within a filter housing assembly. In operation, the controller moves the turn knob of the rotatable valve assembly a one-quarter turn which results in the reversal of fluid flow through the assembly to periodically back flush the filter utilizing fluid from the system inlet. Debris removed from the filter element during the backwash process are immediately discharged from the system through a drain port. Simultaneously, the hydraulic shearing mechanism of the backwash process dislodges and drains debris which may have accumulated on the screen and at the bottom of the lower filter assembly during normal filter operations. The controller then returns the filter assembly to filtration operation by a reverse one-quarter turn of the turn knob of the rotatable valve assembly.

Abstract: Operation of a system for injecting a predetermined amount of a secondary fluid into a primary fluid stream. The system uses a liquid additive injection pump driven by a fluid powered motor that is driven by the primary fluid stream and can be selectively suspended by an on/off switch mechanism. The fluid powered motor includes a housing enclosing a differential pressure piston assembly having a piston movable within housing between upstroke and down stroke positions; a valve mechanism establishing a differential pressure within the housing to produce movement of the piston; an over-center mechanism coupled to the valve mechanism to toggle the valve mechanism between open and closed positions; and an actuating shall coupled to the over-center mechanism.
