摘要： Governor valve device for a pressure fluid operated tool having a ball valve (23, 24), the valve ball (24) of which is provided in a cavity (25), open towards the seal ring (23) of the valve, in a movable piston (26). A spring-loaded member (30) urges the valve ball against the seal ring. By movement of the piston, the ball can be moved out of and into, respectively, a sealing position against the seal ring in order to permit and to prevent, respectively, the passage of pressure fluid to a drive chamber (17) in the tool.

摘要： Pressure fluid operated impact mechanism having a reciprocating working member (5), a stop member (17) and, formed between said members, a drive chamber (18) with seals (15, 16) and a regulating valve (21) co-operating with a supply opening (25) for pressure fluid, in which opening a sleeve (24) can be arranged for the journalling of the valve. The valve blocks the opening when the working member (5) and the stop member (17) have moved a distance away from each other and is open when they are close to each other. Through the valve and the working member, a discharge channel (33, 31, 20, 32) for pressure fluid is provided which is closed when its inlet opening (33) is inside the stop member and is freed when the working and stop members have moved a distance away from each other.

摘要： Lifting hook having a safety latch (10) arranged in a cavity (11) in the hook, which latch can be swung outwards and which is locked in closed position thereby that, by a spring (22), it is displaced to support, with end surfaces of slots (12), against a safety latch shaft (9). A comer portion (28) and a protruding member (23) thereby prevent a swinging outwards of the safety latch by supporting against an inner wall (18) in the cavity and a recess (25), respectively, in an upper wall (19). To open the hook, the safety latch is pulled downwards against the spring force, so that the corner portion (28) runs free from the inner wall and the safety latch can be swung outwards. The safety latch can be arranged to be lowered automatically when the hook is loaded on the commencement of a lifting operation, a suspension shaft (7) thereby, by being displaced in a slot (8) acting on the protruding member (23) so that the safety latch is released and is lowered by the spring force and locked.
