Abstract: A discharge device for media has a housing (10), an operating member (88) manually movable relative to the housing (10) and which, for performing a discharge can be transferred from an unoperated starting position in the direction of an operating direction (1a) into an operated end position and with a locking member (52), which is displaceable relative to the housing (10) between a locked position where it prevents the displacement of the operating member (88) into the end position and a release position in which it permits the displacement of the operating member (88) into the end position.

Abstract: A discharger for a flowable medium, having a pumping device with a pumping chamber which is closed off on one side by a longitudinally movable piston, is provided. The pumping chamber on the piston side is hermetically sealed against an environmental atmosphere outside the discharger by a gas-impermeable and at least partially flexible diaphragm, and the diaphragm, in its marginal region, is fixedly connected to a housing of the discharger. The discharger is used for high sealing requirements against the ingress of impurities.

Abstract: The invention relates to a discharge device for a liquid pharmaceutical medium having a reservoir for storing the medium, a pressurizing device (10) for feeding the medium and at least one discharge opening (80) for delivering the medium to an environment, the pressurizing device (10) having a pressure chamber (16), whose content can be pressurized by a translationally movable piston (14). According to the invention there is a piezoactuator device with a piezoactuator operatively coupled to the piston, or a coil actuator device (30) with an actuator coil (30) and an actuator core (32) to which force can be applied relative to actuator coil (30) by energizing the latter and either actuator coil (30) or actuator core (32) is fixed relative to the piston. Use for producing precisely defined fluid pressures in a discharge device.

Abstract: A discharge device for a liquid pharmaceutical medium has a reservoir for storing the medium, a pressure generator for pressurizing the medium, a discharge opening for discharging the medium and a discharge valve with a valve seat and a valve body movable relative to the valve seat between an open position and a closed position. An electrical valve actuator is provided through which a force can be applied to the valve body through an electrical valve control current.

Abstract: A discharge device for pharmaceutical media has a reservoir for storing the medium, with a discharge opening for delivering the medium to the environment, the discharge opening in a use position being positioned in front of an eye of the user and a feed mechanism for feeding the medium from the reservoir to the discharge opening. A control system with a control unit and a sensor device is also provided. The control system is constructed for detecting an opening state of the eye of the user and/or a viewing direction of the eye of the user and for influencing the delivery of the medium as a function of the detected opening state and/or detected viewing direction.

Abstract: A valve mechanism for a pressure chamber, particularly a pumping device, includes a tappet and a valve disk, in which the valve disk is attached to the tappet. The valve disk is provided on the tappet so as to be movable in relative manner between a starting and an end position.

Abstract: 1. Discharger. 2.1. The invention relates to a discharger for a flowable medium, having a pumping device (40) comprising a pumping chamber (46) which is closed off on one side by a longitudinally movable piston (50). 2.2 According to the invention, the pumping chamber (46), on the piston side, is hermetically sealed against an environmental atmosphere outside the discharger by means of a gas-impermeable and at least partially flexible diaphragm (34), the diaphragm (34), in its marginal region (36), being fixedly connected to a housing (10) of the discharger. 2.3 Use for a discharger having high sealing requirements against the ingress of impurities.

Abstract: 1. Discharger. 2.1. The invention relates to a discharger for a flowable medium, comprising a discharge opening (112) on the one hand, and a medium container or a fastening device (114) for a medium container on the other hand, which are disposed at opposite ends of the discharger in mutual alignment along a principal direction of extent (102) of the discharger, and a pumping device (120) having a pumping chamber closed off on one side by a piston (124), the piston (124) being configured such that it is longitudinally movable along a pumping direction for the generation of a discharge pressure and the pumping direction forming approximately a right angle with the principal direction of extent (102). 2.

Abstract: In a dispenser for liquid media, applicator of the dispenser is fixed to a medium reservoir. A finger rest for actuating the dispenser is configured such that it is axially displaceable relative to this subassembly. As advantageous refinements, a dispenser is proposed whose pump is realized as a user-independent pump, a variety of mechanical realizations being considered advantageous.

Abstract: The invention relates generally to a foam dispenser having a reservoir, a housing, and a chamber. The reservoir delivers fluid to the housing and the chamber through a dip-tube. The chamber moves within the housing in response to fluid pressure or air pressure from the reservoir, allowing air and foamable liquid to enter the chamber. Foam-producing packing material inside the chamber causes the air and foamable liquid to mix and produce foam.
