  • Patent number: 11027300
    Abstract: A fluid dispenser including a body, a chamber coupled to or formed as part of the body and configured to contain a quantity of fluid, and a piston coupled to the body and rotatable within the chamber to different position. The piston is movable relative to the chamber in a first direction along an axis to draw fluid into the chamber, and the piston is movable relative to the chamber in a second direction opposite the first direction to discharge fluid from the chamber. The piston has stroke lengths that are selectable via the different rotational positions of the piston and that are associated with metered quantities of fluid to be drawn into the chamber. An anti-reversal feature is disposed between the piston and the body. The anti-reversal feature inhibits reversal of the piston during movement of the piston in the first direction or the second direction.

  • Publication number: 20140131391
    Abstract: An injection apparatus includes an actuating cylinder, an accommodating chamber, and a volume changing part capable of changing the volume of the accommodating chamber. The actuating cylinder has an operation chamber and a piston accommodated in the operation chamber, and supplies an incompressible fluid to the injection cylinder by forcing out the incompressible fluid inside the operation chamber with the piston. The accommodating chamber is connected to the operation chamber, and holds at least some of the incompressible fluid that flows out from the operation chamber due to the piston being pushed out. The volume changing part expands the volume of the accommodating chamber, at the latest simultaneously with the start of acceleration of the actuating cylinder, and stops the expansion of the volume when the operating speed of the piston of the actuating cylinder has reached a desired speed.

  • Patent number: 7832598
    Abstract: A bulk foodstuff dispenser for dispensing predetermined amounts of foodstuff from a hopper. An auger is driven by a handle capable of movement in two directions, while a clutch allows movement of the auger in only one direction. The forward movement of the handle causes the auger to rotate and move foodstuff forward to be dispensed. The forward movement of the handle is predetermined by setting a stopper, thereby regulating the amount of rotation of the auger and thus determining the portion of foodstuff to be dispensed. A spring returns the handle to its at rest position, so that the dispensing process may be repeated from the same handle position. Gears between the handle and the auger allow the handle to be pulled in a more ergonomically sound way.

  • Patent number: 6886509
    Abstract: The invention relates to a hydraulic actuator for actuating a gas exchange valve (1) of an internal combustion engine, which valve is especially closed by the effect of a spring. The actuator is configured by a feed pump (6) with intermittent and thus variable delivery. The feed pump (6) has a high frequency and can be equipped for this purpose with piezoelectric, magnetorestrictive and/or electrochemical actuators as the feed elements. Optionally, the feed pump (6) can be operated with a stop valve (7) that is disposed downstream of the gas exchange valve (1) and that is controlled or regulated depending on the feed pump.

  • Patent number: 6740295
    Abstract: A method for detecting the type of replaceable piston-cylinder unit mounted in pipetting or dosing apparatus with the help of a code marking on the piston rod head, so as to eliminate the influence of the chain of tolerances piston rod head/piston rod/piston/cylinder bottom/cylinder flange so that, to a certain extent, larger tolerances may be tolerated for the parts of the piston-cylinder units involves generating relative movement between the piston rod head and a detection device, and thereby detecting a reference point on the piston head with the detection device from laterally of the piston head, and generating relative movement between the piston rod head and the detection device and thereby detecting a code marking of the piston rod head in order to determine the type of piston-cylinder unit mounted.

  • Patent number: 5816452
    Abstract: A dispenser gun for selectively dispensing controlled quantities of viscous or semi-viscous materials, and in particular liquid pesticides or insecticides, employs a vacuum driven operating system for discharging and reloading the viscous or semi-viscous materials to be discharged. The dispenser gun is designed to create pressure differentials in adjoining chambers which, in conjunction with a cooperating valve system, enables the discharge of precisely metered quantities of material and prevents continued and undesired discharge or dripping from a discharge nozzle after a preselected quantity of material has been discharged from the dispenser gun. The handle of the device includes structure for pre-selecting one or more predetermined quantities of material to be discharged from the dispenser in repeatable sequences. The dispenser gun also includes structure for removably receiving a replaceable reservoir of viscous or semi-viscous material to be discharged from the gun.
