摘要： A metallic diaphragm is provided within a pump chamber. This diaphragm is oscillated by a stem to Feed liquid medicine. The stem is provided with a plate and a movement of this plate, i.e., a stroke of the stem is limited by a pair of stoppers. Relative position of the paired stoppers at which they limit the stroke is adjusted by providing the paired stoppers with threads which are handed reversely to each other so that the paired stoppers are moved by amounts equal to each other during a change of the relative position. The stem carries thereon a piston which is, in turn, vertically movable within a cylinder chamber into which compressed air is introduced to oscillate the stem. A plurality of such pumps are successively connected one to another, stop valves are connected upstream as well as downstream off the respective pumps and a suck-back pump of the same construction as the liquid feed pump is connected immediately before a liquid filling device.

摘要： A fluid flow control valve is provided with a seal comprising a thin metallic film backed by a resiliently deformable body. The seal is mounted on a closure part which may be either the valve stem or the valve seat. The thin film and deformable body are deformed so as to conform to the surface the metallic film seals against as the valve is closed. As the valve is opened, the deformable body returns to its initial state thus returning the thin film to its initial state.

摘要： A check valve comprises a valve body having inlet and outlet passages and a cavity in which a diaphragm operates. The inlet passage connects with the cavity through an upstream wall partly defining the cavity and the outlet passage connects with the cavity through a downstream wall partly defining the cavity. The diaphragm has an annular sheet metal part which is secured to one of the walls and carries a movable seal. The movable seal cooperates with a sealing element to provide a circular fluid seal. In a first embodiment, the inlet passage connects with the cavity through openings located inside the periphery of the circular fluid seal. In a second embodiment the inlet passage connects with the cavity through openings located outside the periphery of the circular fluid seal. The movable seal may be a sealing surface in which case the sealing element is a seal ring, or the movable seal may comprise a seal ring in which case the sealing element is a sealing surface.

摘要： A flow control device has a case formed in a lower portion thereof with a fluid channel and a disk seat at an intermediate portion of the channel. A spindle housed in the case has a disk at its lower end and a rollable member at its upper end and is biased by a spring to press the disk against the seat. The case is provided in an upper portion thereof with a rotary shaft having an upwardly projecting handle or sidewise projecting lever handle. The shaft has a rollable member seat which is annular or circular-arc when seen from above and which is formed with a protuberance for lifting and lowering the rollable member as placed on its seat. Rotation of the shaft moves the protuberance, which in turn raises the rollable member to lift the spindle and hold the disk away from the disk seat. The rotation of the shaft reliably opens or closes the channel, or reliably effects a change-over between fluid channels. The seal face of the disk is less prone to abrasion or damage, will not displace the handle when the disk is thereby closed and is highly durable. The fluid channel within the device can be completely sealed off, so that the device is advantageously usable as a sanitary valve.

The valve stem comprises an upper bar-shaped member of metal connected to the valve operating member and a lower bar-shaped member made of a fiber reinforced plastic to which the valve element is attached. The upper and lower bar-shaped members are movable upward from a lower end position where the valve element is in a fully open state. The lower bar-shaped member is stop from moving upward at an upper end position where the valve element is in a fully open state. An uppward moving distance of the upper bar-shaped member from a lower end position is made longer than a moving distance of the lower bar-shaped member from the lower end position to the upper end position.

摘要： A flow control device comprising a spindle having a disk at its lower end and a handle at its upper end and spring-biased to bring the disk into pressing contact with a disk seat within a case, a closure having a top wall, and at least one rollable member resting on the upper surface of the closure top wall and mounted on the spindle at an upper end portion thereof projecting upward from the upper surface of the closure top wall. The closure is formed in the upper surface of its top wall with a lower recessed portion for the rollable member to partly fit in, an upper recessed portion for the rollable member to partly fit in and a slanting guide face between the two recessed portions. The rollable member is movable by the rotation of the handle to partly fit into the lower recessed portion to thereby hold the disk in pressing contact with the disk seat or to partly fit into the upper recessed portion to thereby hold the disk away from the disk seat.
