摘要： A hydraulic device having a nut part with a threaded hole which has an internal screw thread with a defined nominal diameter and with a defined, uniform pitch, and having a screw part which has an external screw thread with the same nominal diameter as the threaded hole and with a defined, uniform pitch, which is screwed into the threaded hole. (In hydraulic devices, screw parts, in particular nozzle bodies, are generally adhesively bonded in place, in order to prevent them from becoming detached. Adhesive bonding has certain drawbacks, since the screw threads have to be free of grease, and in the case of nozzles there is a risk of blockages, adhesive can enter the hydraulic circuit and also process reliability is not ensured during application.) There is provided a slight difference between the pitch of the internal screw thread of the nut part and the pitch of the external screw thread of the screw part. This slight difference in pitch while the screw part is being screwed in leads to an elastic deformation of a plurality of thread turns, with the result that the screw part is secured so that it cannot become detached.

摘要： A precontrolled three-way pressure reduction valve having essentially vibration-free operation is encased in a cartridge and has a hollow control piston wherein a working fluid space is formed as a T-shaped cavity within the control piston. In the cavity, there are axial and transverse bores of approximately the same diameter. A groove encircles the control piston, and has a width which is slightly larger than a diameter of the transverse bore, the transverse bore communicating with the groove.

摘要： A two-way insert valve having an insert assembly which can be installed in a receiving bore hole and having a valve cover for closing the receiving bore hole, the insert assembly consisting of two parts, has a bush with several radial passages and with an axial passage and a ring arranged between the bush and the valve cover and has a valve piston by which a connection between the radial passages and the axial passage can be controlled and which is displaceable in opening direction up to a stop. A closing spring urges the valve piston in closed direction. The valve piston in its closed position is guided by the bush at least approximately up to the first end of the bush facing the ring. In this way, the guidance between the valve piston and the bush, the quality of which is determined essentially by the ratio between the guidance length and the guidance diameter, is still sufficiently good even if the radial passages through the bush and the diameter of the valve piston are made very large in order thereby to obtain large opening cross sections of the valve and thus a low resistance to flow.

摘要： Disclosed is a 2-way flow control valve whereby a constant hydraulic fluid volume flow may be adjusted by serial arrangement of a restrictor orifice and a control orifice. In the case of a reverse flow through the flow control valve of the present invention, a check actuating element of the flow control valve may be displaced against the bias of its own check spring in such a way that a bypass channel which bypasses the restrictor orifice can be controlled open.
