HIGH STABILITY REGULATOR
A vent valve opens to provide a fluid path from a regulated pressure port to a vent port, a supply valve opens to provide a fluid path from the regulated pressure port to a supply pressure port. A control piston has a linear cam profile with a vent cam that opens the vent valve and a supply cam that opens the supply pressure valve.
Piston Activated Cartridge Valves and the Components Thereof
Valves, the components used to create valves and, more particularly, to piston-activated cartridge valves are disclosed. The valves include cartridge valve assemblies having a housing and a slidable member, the major part of which is located within the internal space of the housing. One end of the slidable member extends outward beyond the second end of the cartridge housing, and can be contacted by an actuator piston to open the valve. The interior surface of the cartridge housing and the sides of the slidable member are configured so that when the slidable member is in the open position, at least one fluid flow path is provided between the first and second openings of the cartridge housing so that fluid can flow either: (a) from the first opening to the second opening; or (b) from the second opening to the first opening. A system comprising a plurality of insertable devices that are used to create various valve configurations is also provided herein, as are various fluid circuits that can be created using the insertable devices described herein.
Pressure operated shut off valve and fluid distribution system comprising such pressure operated shut off valve
A pressure operated shut off valve for a vehicle fluid distribution system, comprising at least one valve housing, a valve chamber enclosed by the valve housing, at least a first fluid entry port, at least a first fluid exit port, at least a first fluid inlet duct opening into the valve chamber, at least a first fluid outlet duct opening into the valve chamber, at least a first valve body slidably arranged in the valve chamber, the valve body being held closed against the valve seat and being operable by the fluid pressure provided in the inlet duct and acting on the valve body thus lifting the valve body from the valve seat, wherein a mechanical stop selectively blocking or unblocking the valve body upon actuating is provided. A fluid delivery device utilizing such pressure operated shut off valve.
Fuel system control
An evaporative emissions control system includes a first vent valve configured to selectively open and close a first vent, a second vent valve configured to selectively open and close a second vent, a fuel level sensor configured to sense a fuel level in the fuel tank, a pressure sensor configured to sense a pressure in the fuel tank, an accelerometer configured to measure an acceleration of the vehicle, and a controller configured to regulate operation of the first and second vent valves to provide pressure relief for the fuel tank. The controller is programmed to determine if a refueling event is occurring based one signals indicating the fuel level is increasing, the pressure in the fuel tank is increasing, and the vehicle is not moving, and open at least one of the first and second vent valves based on determining the refueling event is occurring.
Fluid distribution apparatus in particular water distribution apparatus
A fluid distribution apparatus comprising a fluid chamber, at least one fluid inlet, a plurality of fluid outlets and a distribution unit, including a plurality of valve elements for closing the fluid outlets and a camshaft supported to be rotatable about a rotary axis, having a plurality of cams for operating the valve elements. The valve elements are formed as valve flaps and the cams of the camshaft are provide to lift the valve elements off of the fluid outlets as a function of a rotary position of the camshaft.
MULTICOMPARTMENT MICROFLUIDIC BIOREACTORS, CYLINDRICAL ROTARY VALVES AND APPLICATIONS OF SAME
One aspect of the invention provides a multichamber bioreactor. The multichamber bioreactor includes multiple planar layers stacked on each other defining at least one chamber and a clamping mechanism. The clamping mechanism includes a housing and retaining means received in the housing and configured to generate a controlled and uniform pressure to secure the stacked multiple planar layers in the housing. Each chamber is implemented from a separate fluidic layer, with each fluidic layer having ports and valves independent of the other layers. The micro fluidic ports can be actuated through a micro fluidic interconnect system utilizing rotary cylinder valves.
NON-ELECTRIC MULTI-CHANNEL VALVE FOR AQUEOUS LIQUIDS OR VAPOR
The present invention relates to the field of non-electric multi-channel valves adapted to provide specific flow patterns to aqueous fluids or vapor, and, more particularly, to non-electric multi-channel valves configured to provide continuous outflow to aqueous fluids or vapor.
REGULATING VALVE WITH INTEGRATED PURGE FUNCTION
A valve includes a valve body provided with a plug, connected to an actuation system, an upstream duct, a downstream duct, and a purge duct provided with a shutter. The plug is movable in rotation about a longitudinal axis in the valve body, so that the rotation of the plug according to a first angular sector defines a flow between the upstream duct and the downstream duct, the rotation of the plug according to a second angular sector separate from the first angular sector shuts off the connection between the upstream duct and the downstream duct, and the rotation of the plug according to a third angular sector included in the second angular sector actuates the shutter so as to allow a flow from the upstream duct to the purge duct.
ELECTRONIC VENTING IN A SADDLE FUEL TANK
A fuel tank system controlled by a control module and constructed in accordance to one example of the present disclosure includes a saddle fuel tank, and a venting assembly. The saddle fuel tank has a first lobe and a second lobe extending on opposite ends of a recessed central portion. The venting assembly comprises a first vent line, a second vent line and a rotary actuator. The first vent line has a first vent port located in the first lobe of the saddle fuel tank near a top portion of the saddle fuel tank above the recessed central portion. The second vent line has a second vent port located in the second lobe of the saddle fuel tank near a top portion of the saddle fuel tank above the recessed central portion.
NON-ELECTRIC MULTI-CHANNEL VALVE FOR AQUEOUS LIQUIDS, VAPOR OR GAS
The present invention relates to the field of non-electric multi-channel valves adapted to provide specific flow patterns to aqueous liquids, vapor or gas, and, more particularly, to non-electric multi-channel valves configured to provide continuous outflow to aqueous liquids, vapor or gas.
