Beschreibung
Zusammenfassung:	A palm unit for an artificial hand, comprising a palm unit body, a motor and a hydraulic pump assembly driven by the motor, both held by the palm unit body. The palm unit body forms a sealed enclosure for all hydraulic parts, including the hydraulic circuit and pumps, and the palm unit body is formed in a single piece, preferably by 3D printing. The hydraulic pump assembly is arranged to switch from a low-pressure configuration to a high-pressure configuration automatically during a closing grip pattern when the pressure in the system increases beyond a threshold value. The palm unit body may have channels for hydraulic actuators for individual digits of the hand.
