Abstract: A piston pump device has a support unit, a pump cylinder, and a pump piston arranged in the pump cylinder. The pump cylinder has a longitudinal center axis, and a cylinder bottom arranged perpendicular to the longitudinal center axis. The pump piston is movable relative to the cylinder bottom, and the pump cylinder is secured on the support unit by a securing unit. The securing unit has a leaf spring, which permits a pivoting movement of the longitudinal center axis of the pump cylinder relative to the support unit. The piston pump device is wear-resistant and runs quietly. When used as a suction pump, the piston pump device additionally permits a controllable air flow until the pump comes to a stop.

Abstract: A fluid-collecting container for receiving a siphoned-off fluid has a closed chamber for a solidifying agent. The chamber can be opened towards an internal space in the fluid-collecting container under external application of force. At least part of the chamber projects into the internal space in the fluid-collecting container. On the outer side of the container, the chamber is closed by an outer wall which can be pressed inwards, and the chamber is open towards the internal space in the fluid-collecting container by the outer wall being pressed in. The internal space continues to be closed to the outside in the region by the outer wall. The fluid-collecting container has a first and a second housing part which together form the internal space in the fluid-collecting container. The outer wall is formed integrally with a wall of the first housing part, the wall surrounding the outer wall.

Abstract: The peristaltic pump is provided with a two-piece housing (2, 3), in which a conveying member (1) as well as a pump tubing section (6) squeezable by the conveying member is received. For fixing the pump tubing section (6) in the housing (2, 3), a tubing holder (4) is provided. Further provided is a connecting element (5) provided with duct shaped connecting sockets (14a, 14b) for connecting tubing sections (15a, 15b). For connecting the pump tubing section (6) to the tubing holder (4), the two ends of the particular pump tubing section (6) are fixed in receptacles (10a, 10b) of the tubing holder (4), which positively enclose the outside of the pump tubing section (6). The connecting element (5) is fixed to the tubing holder (4) by means of a snap-on connection. Thereby, the connecting sockets (14a, 14b) thereof are sealingly connected to the particular pump tubing section (6).

Abstract: An assembly for generating milk foam and for heating milk comprises a milk supply container, a steam generator and a mixing element. The mixing element includes a first steam inlet channel, a necking located downstream of the first steam inlet channel, an air inlet channel opening into the necking and a milk inlet channel. The milk is fed to the milk inlet channel of the mixing element by means of a pump. Moreover, the mixing element is provided with a main channel whose inlet communicates with the necking, whereby the milk inlet channel opens into the main channel downstream of its inlet. Between the necking and the opening of the milk inlet channel, a second steam inlet channel opens into the main channel.

Abstract: An assembly for generating milk foam and for heating milk comprises a milk supply container, a steam generator and a mixing element. The mixing element includes a first steam inlet channel, a necking located downsteam of the first steam inlet channel, an air inlet channel opening into the necking and a milk inlet channel. The milk is fed to the milk inlet channel of the mixing element by means of a pump. Moreover, the mixing element is provided with a main channel whose inlet communicates with the necking, whereby the milk inlet channel opens into the main channel down-stream of its inlet. Between the necking and the opening of the milk inlet channel, a second steam inlet channel opens into the main channel.
