摘要： The invention relates to a reversible torque converter which is intended as a auxiliary device for use in connection with pneumatic, electric and/or hand-operated tools or machines, or which is intended to be incorporated in such machines and tools as an integrated part thereof. The switching or change-over means comprises a radially acting coupling which includes a dogging plate (4) mounted on the input shaft (2), a dogging cage (8, 9) mounted on the output shaft (3), and coupling elements (23) which are active between the two dogging elements and which are arranged for movement between an inner position, corresponding to direct drive, and an outer position, corresponding to a gearing-down drive, when the outward shaft (3) is driven via a planetary gear system (7; 31, 32, 33; 34) which acts upon the coupling elements (8, 9). The coupling elements (23) are spring-biased (10, 11, 12) with a force which must be exceeded in order for a change-over to take place.

摘要： A regulator for regulating the output of an output shaft is discosed, the regulator comprising a number of chambers to and from which working medium can be fed and discharged in dependence upon control means to effect axial movement of the output shaft via pressure transmitting elements.In accordance with the invention, the regulator comprises a number of series-connected units, the units providing fixedly spaced walls to define separated chambers through which the output shaft effectively extends, each chamber having at least one pressure transmitting element therein which is connected directly or indirectly to said output shaft. With such an arrangement the or each pressure transmitting element, when activated, exerts either individually or in unison an axial force on the output shaft substantially corresponding to the sum of the forces exerted on the active pressure transmitting elements. Adjustable stop means are preferably provided for the pressure transmitting elements, and are adjustable via setting and locking means for each length of stroke of the regulator.The regulator may be constructed from a number of module units, each module unit defining a chamber and having a pressure transmitting element of the preceding unit displaceably mounted therein, each element having a shaft co-operating with the pressure transmitting element of the preceding unit and the shafts in combination providing said output shaft.
