Abstract

A locking device for a shaft (4) arranged in a cylindrical bearing (5.1) in a housing (5), said bearing (5.1) comprising a sleeve with a membrane that communicates with a space (7.4) containing a first pressure medium. The first space (7.4) communicates with a primary piston arrangement (7) via the first pressure medium. The primary piston arrangement (7) is also in mechanical connection with a secondary piston arrangement (8) that in turn communicates with a pressure source for a second pressure medium. The shaft (4) can be locked to prevent turning or axial displacement in relation to the housing (5) when increased pressure is applied to the second pressure medium, which in turn causes increased pressure in the first pressure medium and an elastic decrease in diameter in the membrane of the sleeve (5.1).
