The invention relates to a medical-technology valve device for suction and/or flushing lines of medical instruments, particularly instruments for endoscopic surgery, having a valve housing equipped with a through bore-hole and having a valve body, movably positioned in the valve housing, by which valve body the through bore-hole can be locked and opened again, and where the valve body is configured as a piston that can be displaced essentially perpendicularly to the through bore-hole by means of a servo drive, so that a rotary movement of the servo drive can be transformed into an axial movement of the piston. To produce a medical-technology valve device that makes possible a reproducible adjustment of the flow volume that is to be regulated, while allowing a reduction of turbulence, it is proposed with the invention that the servo drive is configured as a hand lever that can rotate around the longitudinal axis of the piston and can be displaced to move the piston from the position that frees the through bore-hole into the position that closes the through bore-hole by an angle of 90 degrees with respect to the longitudinal axis of the piston.

A glass bottle with improved pouring characteristics. In some embodiments the bottle can hold pressurized liquid. The bottle includes a neck with a non-circular cross section. The cross sectional shape of the neck is adapted and configured to provide less turbulence in the liquid being poured out of the bottle, and further to assist in separating the in flow of single phase liquid from the turbulent mixed flow of two phase, gas-liquid substances.

Methods and systems are provided for delivering gaseous fuel as multiple fuel injections split between an intake stroke, a compression stroke, and/or a power stroke to expedite exhaust catalyst heating during an engine cold-start. Fuel injected in the intake and compression stroke is ignited and combusted. The power stroke fuel injections are combusted in the exhaust port to increase exhaust temperature and pressure for faster catalyst light-off.

The present invention provides an axially-rotated valve which permits increased flow rates and lower pressure drop (characterized by a lower loss coefficient) by using an axial eccentric split venturi with two portions where at least one portion is rotatable with respect to the other portion. The axially-rotated valve typically may be designed to avoid flow separation and/or cavitation at full flow under a variety of conditions. Similarly, the valve is designed, in some embodiments, to produce streamlined flow within the valve. A typical cross section of the eccentric split venturi may be non-axisymmetric such as a semicircular cross section which may assist in both throttling capabilities and in maximum flow capacity using the design of the present invention. Such a design can include applications for freeze resistant axially-rotated valves and may be fully-opened and fully-closed in one-half of a complete rotation. An internal wide radius elbow typically connected to a rotatable portion of the eccentric venturi may assist in directing flow with lower friction losses. A valve actuator may actuate in an axial manner yet be uniquely located outside of the axial flow path to further reduce friction losses. A seal may be used between the two portions that may include a peripheral and diametrical seal in the same plane.

The rotor includes a rotor first end, a rotor second end, an outer surface, and an inner surface that defines an inner chamber in fluid communication with the purge gas outlet. The tubular flow passages are formed in the rotor and extend between the rotor first end and the rotor second end. Each tubular flow passage includes a fluid inlet that is disposed adjacent the rotor first end and in fluid communication with the liquid/gas inlet, and a fluid outlet that is disposed adjacent the rotor second end and is in fluid communication with the liquid outlet. The gas flow passages are formed in the rotor, and each provides fluid communication between one of the tubular flow passages and the inner chamber.

An improved pot and pan washing machine is provided including a low suction intake manifold and a partition for capturing a substantial portion of the wash action of the washing machine within a segregated area.

The present invention includes apparatus and methods for disk dampers with an inlet edge and/or an outlet edge, oriented and shaped to control airflow within the hard disk drive. The inlet edge and the outlet edge reduce the airflow turbulence at the actuator assembly. This improves the Position Error Signal (PES), as the read-write head accesses a rotating disk surface. The outlet edge may preferably be curved and oriented at an oblique angle with respect to the angular rotation of the disk(s) in the hard disk drive. The outlet edge may preferably extend over a section of a sector angle. The inlet edge may preferably be oblique, which helps to slow down the overall velocity of the airflow into the disk damper. This allows the tip of the inlet edge to be positioned closer to the actuator assembly than previously possible.

The present invention concerns a regulating valve (1) of the type preferably used for dynamic regulation of fluid-borne systems, such as central heating systems in housing and industrial buildings or cooling facilities, where the control valve is provided with a valve housing (2) with an inlet (3) and an outlet (4), where a valve insert (5) with an orifice means (12) is provided in the valve housing (2) by which the flow in the regulating valve can be regulated, and where additionally there are detecting means (6, 7) for detecting either supply pressure or discharge pressure and another pressure, respectively. The regulating valve is provided with a modular valve insert (5) which at least includes a differential pressure regulator (9), a venturi (10), a throttle device (11) and a coupling member (13) for an actuator, where the various modules are made with interacting joining means, preferably with snap-action joints. A valve insert (5) may thus be built up of respective modules, where the modules are selected individually with the most suitable specifications for the individual task. It is thus not required to make as many different combinations of valve inserts since they are combined modularly according to need.
