Display device (16) is provided for displaying the flow rate acquired on the flowmeter (8).

Abstract: Scissors comprising two scissor components, which are connected via a pivot, and a spring whose spring effect forces the two scissor components apart into an open position. In order to make such scissors more universally usable, means (10) for disabling the spring effect are also provided.

Abstract: A machine for the preparation of a hot drink with a housing and a brewing chamber, wherein the housing is provided with a connection region through which the brewing water is passed to the upper part of the brewing chamber. In order to seal the inflowing brewing water against the environment at the connecting point between the housing and the brewing chamber in a simple, economical and wear-resistant manner without complex locking mechanisms being needed, a seal is inserted into the upper part of the brewing chamber, wherein the seal and the connection region are automatically pressed together when the brewing chamber is inserted into the machine such that the connecting point between the connection region and the upper part of the brewing chamber is sealed against the environment.

Abstract: Described is a coffee machine (1) comprising a brewing member (5, 5′), a support surface (15) for ground coffee and a member (3, 6, 7) for applying water to the ground coffee, in which it is possible to level off the ground coffee positioned on the support surface (15) in a constructionally simple and generally applicable manner to obtain a layer having a substantially uniform thickness. To this end there is provided a member (22, 24, 25, 122, 222, 322) which guides water in a purposefully non-uniform manner over the ground coffee such that the ground coffee is distributed over the support surface (15) in a layer having a substantially uniform thickness.

Abstract: A coffee machine (1) with a brewing apparatus (7) is described which has a brewing chamber (9) and a piston (37) being movable to and fro herein. One of the front sides of the brewing chamber (9) contains an opening (44) which is cleared by a closing element (8) in one of its positions (I) for apportioning coffee powder and is closed in another position (II). A stripper (48) is provided for stripping off and ejecting the used up coffee grounds. In order to constructionally simplify such a coffee machine and to make it operatively more reliable and more robust, it is suggested to move the closing element (8) only relative to the brewing chamber in a plane extending in parallel to the opening (44) and to couple the stripper (48) to the closing element (8) in its movement.

Abstract: A brewing means (1) for a coffee machine with a brewing chamber (3) is described, which is disposed in a housing (2) provided with an opening (9) on a front side. The opening (9) can be closed by means of a closing element (10) sealed against the opening. A hot water line (11) is furthermore provided, which supplies hot brewing water to the brewing chamber (3) under pressure and supports at the same time the sealing of the opening (9). In order to design such a brewing means (1) in such fashion that the service life of the seal (21) can be increased, it is suggested that the seal (21) comprises a flexible membrane disposed between a sealing chamber (22) connected to the hot water line (11) and a sealing seat (19), which can be arched and pressed against the sealing seat by means of the pressure.

Abstract: A coffee machine with a brewing apparatus is described which contains a brewing vessel disposed removably and insertably on a support by detachable fasteners. A piston driven by a motor via a piston rod and a gear pin is movable within the interior of the brewing vessel. In order to facilitate the removal and insertion of the brewing vessel in a given direction for cleaning purposes and to be able to also exchange the brewing vessel, if required, the piston is connected to the gear pin via a separable coupling, which can be separated or coupled by removal or insertion movement of the brewing vessel in the given direction so that the brewing vessel can be removed and inserted together with the piston as a unit.

Abstract: A coffee machine having a flow heater in the hot water line that effects additional heating of a residual amount of hot water left in the line after termination of the coffee-making process to convert it to steam and press out any water remaining in the used grounds to dry them for easy removal.

Abstract: A coffee percolator having a brewing chamber wherein at least one of the boundary wall surfaces of the brewing chambr is adjustable transversely of the direction of flow of the hot water through the coffee powder so that the thickness of the coffee powder bed in the direction of flow may be kept substantially constant for the coffee charges of varying size. The coffee percolator may include a brewing sieve having a support sieve with openings of a size exceeding the dimensions of the ground coffee particles and a fine sieve supported on the side of said support sieve facing towards the brewing chamber and having openings of a size smaller than the dimensions of the ground coffee particles.

Abstract: A steam pressure cooker (1) is described, which is provided with a lid (2) and a pressure relief valve (8), comprising a valve seat (7a), a valve body (9) adapted to have a load applied thereto in the direction of the valve seat (7a) by means of a spring (11) and an adjustable spring abutment (12), which is adapted to be displaced from an operative position in which the valve body (9) is pressed onto the valve seat (7a) to a steam-discharge position in which the valve body (9) is relieved of the load to such an extent that the steam can escape and which, for the purpose of cleaning, can be removed from the lid (2) to such an extent that the pressure relief valve (8) is freely accessible.
