1. Inter-fluid transmitter for the supply of pressure to a second supply circuit (39) driven with a second fluid from a first supply circuit which is driven with a first fluid and has a pressure source, with a housing (10, 11) having a working cylinder (16) and a working piston (30) with return spring (57) which is guided in the working cylinder and at the end face bounds two working chambers (21, 42), one of which, as the drive chamber (21), can be acted upon (P) by the pressurized first fluid and released (R), and the other of which, as the pump chamber (42), can be filled with the second medium on the stroke of the working piston (30) and can be emptied again by means of a non-return valve (33), characterized in that the housing (10) of the working cylinder (16) and the working piston (18) are each in two parts, in that in each housing part (10, 11) a piston part (17, 30) is guided in a cylinder section (15, 292) and for shutting off the working chamber (21, 42) bounded by it is sealed off from the inside wall of said section, and in that when the axes of the cylinder sections (15, 292) are in line with each other and piston parts (17, 30) rest with their end faces against each other under the effect of the return spring (57) the two housing parts (10, 11) rest with their end faces against each other and are connected to each other.
