    • A check valve includes a valve body having an inlet end through which air enters the valve and a valve cavity extending through the valve body and leading to an outlet end. A valve assembly is located at a position that enables control of the flow of air through the valve cavity. The valve assembly includes a tapered section having a cross section that increases in diameter in a direction that is downstream from the inlet end of the valve and which may be included as part of a plug. An elastomeric seal is mounted around the tapered section to reciprocate on the tapered section, with the tapered section biasing the elastomeric seal to a normal position at which the seal comes into sealing contact with both the valve body and tapered section to prevent the downstream flow of air from the inlet end out the outlet end.

    • A liquid driven pump includes a driving-liquid accelerating nozzle (11), which opens out into a pump chamber (5, 7) having an outlet part (7) positioned coaxially with the nozzle. Opening out in the pump chamber (5, 7) is an evacuation line (9, 10) which is intended for connection to a space to be evacuated. The outlet part (7) of the pump chamber discharges into a drainage chamber (22) which is coaxial with the outlet part and which has an abrupt increase in cross-sectional area in relation to the outlet part. The drainage chamber has arranged downstream therein net-like elements (15) which are through-passed by the liquid. The relationship between the smallest cross-sectional areas of the nozzle (11) and the outlet part (7) respectively and the distance between the nozzle orifice and the drainage chamber (22) are so mutually adapted that the whole of the diffusion process, or at least practically the whole of the diffusion process will take place through the agency of the net-like elements (15). The smallest cross-sectional area of the outlet part is from 1.4 to 4.8 times larger than the nozzle orifice area, and the drainage orifice (17) is substantially circular in shape and has an area which exceeds the total open mesh area of the net-like elements and is from 15 to 45 times larger than the area of the nozzle orifice.

    • An improved mixing unit (170) and check valve (930A, 930C) for a fluid pumping system wherein gradient proportioning is performed at high pressure are described. The mixing unit has lining means disposed on the inner surface of the chamber (406) for preventing frictional contact between the steel of the chamber and the surface of the rotor (416). The lining means is formed of a polymeric material selected for frictional compatibility with the rotor, and avoids formation of undesirable particulates by friction with the rotor surface. The check valve (930A, 930C) has a poppet (932) comprising a midsection (938) dimensioned to provide forward and rearward surfaces against which fluid flow will exert force, a first arm (934) extending transversely from the midsection first side toward the valve inlet (954), a second arm (936) extending transversely from the midsection second side toward the valve outlet (950), and first and second resilient seals (944, 946) respectively annularly disposed about the first and second arms. The resilient seals are formed of a resiliently compressible material, and have an uncompressed thickness which is somewhat greater than the first arm length.
