An apparatus for making espresso coffee has at least one delivery unit, a hydraulic circuit connected to the delivery unit, and a driving device having a lever movable between a first position and a second position. The delivery unit has a first cylinder with a piston slidably mounted therein and at least one braking device having a second cylinder. The second cylinder is connected to a circuit independent of the first cylinder. The movement of the first cylinder charges water and discharges water from the first cylinder.

A cold brew coffee brewing machine is provided. The cold brew coffee brewing machine may have an upper chamber and a generally identical lower chamber wherein the upper chamber and the lower chamber may be, for example, common mason jars. A filter unit may be secured between the upper chamber and the lower chamber when the coffee brewing machine is in use. A hand pump may be connected to the filter unit and may provide air pressure to the upper chamber. The lower chamber may then be secured to the filter unit and the entire device inverted. Both gravity and air pressure created by the hand pump may be used to force the water through the filter unit so that the drinkable coffee enters the lower chamber.

A device for the preparation of a hot beverage comprises a water reservoir, a flow heater and a brewing device. The water reservoir has a connection element for cold water. The water reservoir is fluidly connected to the flow heater, so that the flow heater can be filled with the cold water from the water reservoir.

According to a coffee maker of the present invention, the multi-joint linkage of a drive mechanism is alternately arranged three-dimensionally in a front-back direction, and thus stronger pressing force may be applied and the pressing force may be uniformly transferred to both sides of the pressing portion. When a user simultaneously presses the drive mechanism with his or her both hands, the pressing force applied by the right drive mechanism and the pressing force applied by the left drive mechanism may be uniformly transferred to the pressing portion without loss, and thus the availability of the pressing force may be increased. The coffee maker according to the present invention is robust, has desirable durability, and may be aesthetically decorated with metal and transparent plastic materials.

A hand-press coffee machine comprising a water tank, a hand pump which is disposed at the upper end of the water tank, and a brewing component which is connected to the lower end of the water tank; a water hole is disposed at the point where the water tank and the brewing component are connected; the hand pump is used to pump the water in the water tank into the brewing component through the water hole; a unidirectional valve, which is disposed in the water hole between the water tank and the brewing component, is set to merely allow the water in the water tank to flow into the brewing component; the present invention can effectively protect the coffee powder from being pre-soaked.
