Abstract: In a radiator valve a second throttle point which is formed by a gap (119) between an annular face (114) surrounding the valve seat and the end face of an insert (113) is located downstream of a first throttle point between the valve seat (108) and the closure member (109). The gap (119) is axially offset with respect to the valve seat (108). In particular, the valve seat (108) projects beyong the annular face (114). In this manner, valve noise can be considerably reduced.

Abstract: A control valve (1) is disclosed, having a housing (2) which has an input port (3) and an output port (4) that are connected to one another by a flow path in which a throttling device is arranged. It is desirable for such a control valve to be able to hold a volume flow constant, irrespective of the load pressure at the output port (4). For that purpose, the throttling device comprises a series connection of a first throttle (27), the passage of which is externally adjustable, and a second throttle (28), the passage of which is adjustable in dependence on pressure.

Abstract: A hydraulic axial piston motor (1) is disclosed, having a cylinder drum (4) which is connected, so that it is non-movable axially, to a shaft (3) and so that they rotate together, and which has at least one cylinder (5), for each cylinder a piston (6) arranged in the cylinder, which piston bears at its end projecting from the cylinder drum (4) against a swash plate (8) via the intermediary of a slider shoe (7), a pressure-applying arrangement (9) for holding at least one slider shoe (7) against the swash plate and a control plate (12) with control kidneys. It is desirable for such a motor to be reliably operable even when the shaft is provided with axial play. Leakages in particular are to be avoided. For that purpose, the pressure-applying device (9) is mounted so as to be axially movable relative to the cylinder drum (4). A pressure plate (13) that is axially movable relative to the cylinder drum (4) is arranged between the control plate (12) and the cylinder drum (4), this pressure plate having for each cylinder a through-opening (14) which is connected in a fluid-tight manner to the cylinder (5). Furthermore, between the pressure-applying device (9) and the presssure plate (13) there is provided an expanding device (18) which acts on the pressure-applying device (9) and the pressure plate (13) with oppositely directed forces.

Abstract: A valve (1), which has heat-sensitive parts, has at least one connecting tube (3, 4, 5) to which a pipe is arranged to be soldered using local heating. The connecting tube (3, 4, 5) consists of a material of such low thermal conductivity that the heat-sensitive parts remain below the limit temperature as the heat required for soldering is applied. No cooling measures are therefore needed while the pipe is being joined by soldering.

Abstract: In a thermostatic valve for a radiator, a tappet is arranged to be displaced axially by a thermostatic element (K), and in turn displaces a closure member (3) by way of a pin (6). Between the tappet (16) and the pin (6) there is arranged a stroke amplifier (23) having two ramps (25, 26) and an amplifier element (24) arranged therebetween. On axial movement of the tappet (16), the amplifier element (24) executes a transverse or rotary movement. This causes the distance between the tappet (16) and the pin (6) to change. A stroke amplification is achieved in this manner.

Abstract: A security device for a thermostat (1) for securing the thermostat (1) against theft and against damage and for securing a rotary knob (7) on the thermostat housing (6), which knob serves for adjustment of the desired value, against a predefined rotation, contains a security sleeve (4) which on the one hand engages over the coupling between the thermostat housing (6) and the adjusting valve and on the other hand engages over the rotary knob (7) and is arranged to be non-rotatably connected to the thermostat housing (6) and the rotary knob (7). So that the rotary knob (7) can be locked not only at a predetermined desired value, but can also be adjustable over a selectable range of desired values which is smaller than the normal adjustment range, provision is made for a coupling element (5) to be arranged between the rotary knob (7) and the security sleeve (4); in different rotated angular positions in relation to the rotary knob (7) the coupling element is either arranged to be non-rotatably coupled to the knob and to the security sleeve (4), or allows a limited rotation of the rotary knob (7) relative to the thermostat housing (6) for an adjustment of the desired value between two desired value limits, of which at least one limit is selectable by the non-rotatable coupling of the coupling element (5) in a rotated angular position, corresponding to this desired value limit, relative to the rotary knob (7).

Abstract: A hydraulic machine (1) is disclosed, with an annular gear (3) with internal teeth (6, 7) and, eccentrically mounted in the annular gear, a gearwheel (2) with external teeth (4, 5) which engage with the internal teeth, the external teeth comprising one more tooth than the internal teeth and the contour of the external teeth being formed by an envelope of a system of generating circles (14), the midpoints of which lie on a trochoid (9) which, as a rolling circle (10) rolls without slipping on a base circle (11), can be generated by the movement of a point lying on a radial ray of the rolling circle co-rotating with the rolling circle. A method of producing the contour of a gear wheel of such a machine is also disclosed. In such a machine it is desirable to realise a satisfactory inner seal and low Hertzian stresses. To that end, the spacing of the point from the midpoint of the rolling circle (10) is larger than the radius of the rolling circle (10). The tooth form can then be formed by the end points of a system of line segments which are located at right angles to the trochoid (9) and are the same length as the radii of the generating circles (14), wherein the trochoid (9) encloses a closed inner face and separates it from an outer face and several intermediate faces, and the line segments are arranged only in the inner face.

Abstract: A hydraulic axial piston machine is disclosed, having an inclined plate (7), on which a slider shoe (9) of at least one piston slides on relative movement between a cylinder body (2) receiving the piston and the inclined plate (7), and a pressure plate (10) articulated on the cylinder body (2) and holding the slider shoe (9) in engagement with the inclined plate. It is desirable for such a machine also to be operable with a hydraulic fluid that has no lubricating properties. For that purpose, between the pressure plate (10) and the cylinder body (2) there is arranged a bearing element (18) with a bearing surface (19) of plastics material, which slides with low friction on a counterpart (15) made of metal lying against the bearing surface (19).

Abstract: A hydraulic piston machine is proposed, with a cylinder body (1), which comprises at least one cylinder (2) with a piston (3) movable therein, and a control counter-plate (7) which engages the cylinder body (1) by way of a contact surface (6) and, on relative movement between the cylinder body and the control counter-plate parallel to the contact surface, connects the cylinder in dependence upon its position with inlet and outlet channels (11, 12) respectively, the control counter-plate (7) and/or the cylinder body (1) being provided, at least in the region of the contact surface (6, 9), with a friction-reducing layer (13). A machine of that kind should be inexpensive to manufacture yet should operate reliably even when the hydraulic fluid has no or only slight lubricating properties. For that purpose the friction-reducing layer (13) is in the form of an injection-moulded part.
