Abstract

In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) at least two helical pressure springs (57, 58) act between the two frames (12, 31) and are each arranged in a circumferentially closed duct (45, 46) provided in one (31) of the two frames (12, 31), which duct also accommodates a piston-like pressure member (47, 48) which projects from the relevant duct (45, 46) and bears against the other one (12) of the two frames (12,31).
