Patent
Parker Hannifin | Date: 2016-07-28

A self-contained monitoring assembly and method of self-cleaning for monitoring a process fluid. The assembly and method includes a closed loop of fluid flow having at least one housing having a sensor chamber, a sensor positioned within the sensor chamber, an injection nozzle receiving the process fluid through an inlet fluid passage and discharging the process fluid through an outlet passage into the sensor chamber, and a drain passage. The injection nozzle is positioned at an oblique angle relative to a contact surface of the sensor such that the contact surface is impinged by the process fluid. Impingement by the process fluid against the contact surface allows measurement of the process fluid by the sensor and cleans the contact surface.

A hybrid drive vehicle control method and apparatus for a hybrid drive vehicle having a prime mover, drive wheels, a hybrid mechanism having an energy storage device, and an electrical controller is provided. The apparatus and method collect vehicle data characteristic of how the vehicle is operated, and compare the collected vehicle data to prescribed data, the prescribed data corresponding to a desired operation of the vehicle. A propulsion power limit of at least one of the hybrid mechanism or the prime mover is set based on the comparison.

A kit and method for monitoring for the presence of catalyst fines in heavy fuel oil (HFO), including: a) providing a sample of HFO; b) mixing the HFO sample with a diluent composition comprising a non-polar solvent and with an aqueous reagent composition to provide a test sample, wherein the aqueous reagent composition comprises at least one water soluble inorganic salt and at least one water soluble base; c) allowing phase separation to occur in the test sample to provide an aqueous phase and an organic phase; and d) inspecting the aqueous phase of the test sample for the presence of catalyst fines. The diluent composition can consist of a non-polar solvent selected from mineral spirits, kerosene, naphtha, and heavy distillate and a phase transfer agent selected from tripropylene glycol monomethyl ether, ethylene glycol, propyl alcohol, isopropyl alcohol and butanol.


Patent
Parker Hannifin | Date: 2016-11-30

A vehicle includes a pump having a swash plate tiltable about a swashplate tilt axis, wherein rotation of the swashplate changes the title angle and effects a change in volumetric displacement of the pump. A controller is operatively coupled to the swashplate to effect rotation of the swashplate, the controller including a processor and memory, and logic stored in the memory and executable by the processor, the logic configured to automatically control at least one vehicle characteristic independent of a user input command.


Patent

A segmented sealing assembly includes a first sealing segment and a second sealing segment, the first and second sealing segments having opposing mating components that are moved into a contact engagement to form the sealing assembly. The first and second sealing components include a first primary seal component on the first sealing component and a second primary seal component on the second sealing component that form a primary seal when the sealing segments are moved into the contact engagement. The sealing assembly includes compression elements on each of the first and second sealing segments. Compression of the compression elements exerts a force that moves the opposing mating components into the contact engagement. The mating components may be configured as tapered tongues having opposing slopes. A plurality of interlacing sealing beads may be provided on the tongues to provide a secondary seal within a gap between the tongues.


A spool component for use in a spool valve has a cylindrical body including a first diameter portion and a second diameter portion, the first diameter portion having a diameter that is larger than a diameter of the second diameter portion. A metering notch is cut into the first diameter portion and extends toward the second diameter portion. The metering notch includes a first angle cut and a second angle cut that are sloped at different depth angles toward the first diameter portion. A spool valve assembly includes a housing defining a bore, and the spool component, which is moveable within the bore along a stroke distance comprising a metering band for metering a flow of fluid across the spool component. The metering notch provides precise metering of the flow of fluid across the spool component based on the different depth angles of the cuts in the metering notch.

A fuel pump includes a cartridge removably received within a canister. The cartridge includes a motor assembly, and a pump assembly that includes a centrifugal pumping element and outlet porting from the centrifugal pumping element. The motor drives the centrifugal pumping element to generate a flow of fluid through a main flow pathway between a pump inlet and outlet through the outlet porting of the pump assembly. The cartridge further includes a pressure relief valve that is movable between a closed position and an open position, and defines a pressure relief flow pathway integrally within the cartridge from the outlet porting to inlet porting of the centrifugal pumping element. When pressure within the pump assembly exceeds a threshold pressure, the pressure relief valve moves from the closed position to the open position to permit a relief flow of fluid through the relief flow pathway. The fuel pump may be employed as part of an aircraft fuel system.


Patent

A valve (10) for a refrigeration system has a valve body (12) with an inlet port (14), an outlet port (16), and walls forming a main cavity (22). A cartridge (20) is configured to reside within the main cavity (22) and has a cylinder in which a piston (30) is movable in a first direction to permit fluid flow from the inlet port to the outlet port and in a second direction to impede fluid flow from the inlet port to the outlet port. A port plate (18) is removably mounted to the valve body for closing an end opening of the main cavity through which the cartridge can be inserted into and removed from the main cavity, and has a plurality of functional ports (26a, 26b, 26c). Each of the functional ports is configured to accept at least one of plural valve control elements (28) for controlling the piston to permit or impede the fluid flow from the inlet port to the outlet port, and is disposed at an acute angle relative to a central axis of the piston, so that a functional component mounted to a respective functional port will not block access to fasteners securing the port plate to the valve body so that the port plate can be removed from the valve body without removal of the control element(s) from the port plate.
