Abstract: A continuous operation metering valve, based on true volumetric positive displacement technology, uses an innovative dual rack and drive pinion design that enables the valve to dispense from one meter chamber while the other meter chamber is filling. This provides greater dispense cycle rates because it does not require a fill or reload period. With an optional encoder-controlled motor, the inventive metering valve is capable of almost unlimited precision dispensing with “on-the-fly” adjustment capability. The metering valve is easily disassembled and cleaned, using stainless steel wetted path components and Teflon seals for the widest range of chemical compatibility. An integral electronic board, mounted to the side of the valve, may be utilized to control the 4-way directional valve and motor direction (when not using a rotary encoder control).

Abstract: A method and apparatus for metering and mixing multi-component plastics, in particular polyurethane, in which two or more hydraulic piston and cylinder units (A.sub.1 and A.sub.2) for each component, operate periodically by a balanced procedure. The pressure for the second piston and cylinder unit which takes over metering is equilibrated, before the beginning of the metering procedure, with the pressure of the first piston and cylinder unit which is in the process of metering. Switching from one piston and cylinder unit to the other (e.g. from A.sub.1 to A.sub.2) takes place in such a way that metering is taken over by the second piston and cylinder units at the same time as the first piston and cylinder unit is switched off. This is achieved by providing a pilot valve which has zero overlap and inevitably releases the component stream from the first piston and cylinder unit at the same time as the other piston and cylinder unit is switched off.

Abstract: Flow control of a shear-sensitive, i.e. pressure gradient degradable, liquid from a high pressure source to a lower pressure discharge is achieved by controlling the liquid's exposure to a degradation pressure gradient. Two displacement chambers are provided and connected by a control conduit. First and second movable barriers in the first and second chambers respectively contain a separate controlling liquid. A pressure and flow control valve is included in the control conduit. Incoming pressurized controlled shear-sensitive liquid flows into the first displacement chamber to displace the first barrier which displaces controlling liquid through the flow control valve. Shear-sensitive liquid is dispensed at relatively lower pressure from the second chamber in response to movement of the second barrier driven by the controlling fluid coming from the control conduit into the second chamber.

Abstract: A device for providing pulsation-free feeding of a liquid medium from a supply container to a consuming device for use in a road-marking machine is disclosed. Two statically-operating reciprocating-piston pumps are arranged between the supply container and the consuming device such that when one pump is on suction stroke, the other is on a feed stroke. The pump flow rate is proportional to the drive speed of the road-marking machine and the feed flow of each pump has zones which overlap the other. The feed sides of the pumps are connected to a change-over means which alternately connects delivery flows from the pumps to the consuming device and also connects the pressure side of the pumps simultaneously to the consuming device and to the supply container, which prevents pressure flow fluctuations as the back-pressure to each pump is the same.
