Abstract: A discharge head for a liquid dispenser having a base and a push actuator. The discharge head has a pump device, which has a malleable pump chamber component open on both sides, fastened to the base and to the push actuator and encloses a pump chamber having a variable volume. The pump device has inlet and outlet valves. The discharge head has a ventilation opening and a ventilation valve. The ventilation valve on the base has a peripheral valve web raised via a surrounding cover wall of the base and the inside of which forms a peripheral valve surface. To ensure a reproducible behavior of the ventilation valve, a reinforcement structure is provided on the cover wall in the form of a peripheral reinforcement web, and/or the peripheral valve web is designed as part of a sleeve-like structure, which forms the peripheral valve web above the cover wall.

Abstract: An internal heat exchanger (IHX) assembly for use in a vehicle includes at least three plates joined together to form two or more separate compartments or channels and at least one flat structure on an external surface of the IHX assembly. One compartment or channel contains a high pressure fluid and the other compartment or channel contains a low pressure fluid. The compartment or channel containing the high pressure fluid is in thermal communication with the compartment or channel containing the low pressure fluid, such that heat is transferred from the high pressure fluid to the low pressure fluid. The IHX assembly acts as a structural member in the vehicle upon which one or more refrigerant components are mounted onto the flat structure.

Abstract: Cream dispenser for topically dispensing liquid onto the skin of a user including a liquid store, a discharge head that has a discharge opening and a hinged lid to protect the discharge opening. The dispenser has a multi-part design of the discharge head in order to limit, in a haptically satisfactory way, the movability of a release button of the discharge head and a special relative arrangement of the locking edges on the discharge head and on the hinged lid opposite a joint of the hinged lid in order to prevent the sharp-edged locking edges from coming into contact with the skin while cream is being discharged onto the skin.

Abstract: A liquid dispenser for cosmetic liquids having a liquid reservoir and an applicator. An outlet channel connects the reservoir to the applicator, the outlet channel being formed either valveless or with an outlet valve. The liquid dispenser has a pressure generating device which pressurizes liquid in the reservoir for conveyance through the outlet channel to the applicator. The pressure generating device has an air pumping device which feeds and an actuating pressure chamber. The actuating pressure chamber adjoins, and is separated from, the reservoir by a displaceable wall so that an overpressure in the actuating pressure chamber leads to an overpressure in the reservoir. The air pumping device has manual actuator, allowing air to be pumped into the actuating pressure chamber by the actuator, so that the overpressure in the actuating pressure chamber and in the reservoir rises sufficiently to convey liquid from the reservoir to the applicator.

Abstract: A discharge head for a liquid dispenser for discharging cosmetic products which has a base to be secured to a liquid storage. The base has a coupling device in the form of a thread or a latching coupling device, for coupling to the liquid storage. The discharge head has a sponge carrier with a sponge receptacle in which a sponge is arranged. The sponge carrier is movable in a translationally guided manner with respect to the base and has a hollow connector inside which a liquid channel is provided that connects the liquid storage to the sponge receptacle. This liquid channel is provided with an outlet valve, which is opened by moving the sponge carrier in the direction of the base, such that liquid can flow freely out of the liquid storage into the sponge receptacle.

Abstract: A data transmission system may comprise a first transmission chain comprising a first transmission power controller, the first transmission power controller being configured to operate in an open loop power control mode or in a closed loop power control mode; a second transmission chain; and a power control mode selector configured to select the first transmission power controller to operate in the open loop power control mode or in the closed loop power control mode based on at least one quantity indicative of interference induced by the second transmission chain in the first transmission power controller when operating in the closed loop power control mode.

Abstract: Discharge head for a liquid dispenser including a housing, a coupling device for attachment to a liquid store, a discharge opening through which liquid is dispensed and an outlet channel extending from an inlet region, pointing in the direction of the liquid store, up to the discharge opening and via which the discharge opening is supplied with liquid. A throttle device is arranged in the outlet channel and includes a throttle channel for reducing liquid pressure and/or liquid flow through the throttle device. The throttle device is designed in the form of a dynamic throttle device, in which a free cross section of the throttle channel is reduced in size with increasing pressure prevailing at the throttle device, or with greater liquid flow flowing through the throttle device.

Abstract: Dispensers having a liquid reservoir filled with a main liquid and having a dispensing head, with a dispensing opening and a dispensing channel, which connects the reservoir outlet to the dispensing opening. The dispensing head can be pressed down to actuate the switching valve or the conveying device. The liquid dispenser has a replaceable exchange unit, which, in a functional state, forms the dispensing channel at least in some sections. The exchange unit has a mixing chamber, with an addition medium and an inlet and an outlet separated from the inlet. The exchange unit is part of the dispensing channel such that the inlet is communicatively connected to the reservoir outlet and the outlet is communicatively connected to the dispensing opening. Furthermore, the exchange unit has closures at the inlet and at the outlet to close the mixing chamber.
