Abstract: A controlled sliding valve comprises a valve housing with cylindric bore, in which a slide controlling a hydraulic flow reciprocates by an adjusting force. The sealing surfaces between the slide and bore form a sealing gap converging in the flow direction, and the size of the flow is controlled between a throttling edge and longitudinal control grooves (7, 8; 44, 45) in the slide with variable cross-sectional area in the direction of movement of the slide. A centering spring retains the slide in closing position. In order to obtain low adjusting forces, to control the volume so as to be substantially constant and independent of the pressure drop over the valve, and to maintain low leakage past the slide, the valve housing includes a central chamber (6) provided with a port (3), and on both sides of said central chamber two control chambers (9, 10) with ports and each with a sealing gap (11 and, respectively, 12) spaced from each other. Either of the central chamber (6) and two control chambers (9, 10) communicates in all adjustment positions with the control grooves (7, 8), which can be caused to open to only one of the sealing gaps (11 or 12) at a time. The centering spring (13) acts centering for the slide from the positions of movement where there is flow connection between the central chamber (6) and either of the two control chambers (9, 10), and the flow direction is in the converging direction of the sealing gaps (18, 19) whereby, thus, the hydraulic flow can pass between the central chamber (6) and one of the two control chambers (9, 10) at a time in the direction determined by the sealing gaps having to converge in the flow direction.

Moreover, the sealing ring (1) is thin having such a small radial middle height (hm) according to the formula hm = A/b, where A is the cross section area of the sealing ring and b its radial width, that the sealing ring has maximum a surface pressure p against the other detail (4) which considering the material and surface structure of this detail and the lubricating qualities of the medium can be accepted according to the formula p = (2 . hm . DELTAd/d2) . E, where E is the coefficient of elasticity of the sealing ring, d its diameter and DELTAd its diametrical elastic deformation. Moreover, the radial height (h) of the sealing ring (1) along its side surfaces (6, 7) facing the gap (12) between the details (3, 4) is at least as large as the radial height of the gap.

Abstract: A heat exchanger for the exchange of heat between two media (Ma, Mb), each of which flows through a respective one of two chambers (A, B) mutually separated by a medium-impervious partition wall (5) made of thermal conductive material. The interior of each of the flow chambers, or at least of one flow chamber, is divided into a large number of medium-flow passages, which are connected in parallel with respect to the flow of medium passing therethrough. The flow passages (13, and 17) have a substantially rectangular cross-section having a flow area which is so adapted in respect of the medium flowing therethrough that the flow in the passages is substantially laminar throughout the whole length of the passages, without a central turbulent zone. The passage walls defining the flow passages comprise a highly thermal-conductive material and are formed integrally with, or in good heat-conducting contact with the partition wall (5) located between the two flow chambers (A, B). The width (s) of the flow passages parallel with the partition wall is at most 1.5 mm and preferably less than 1.00 mm. The height (h) of the flow passages, and therewith the passage walls, at right angles to the partition wall is normally less than 8 mm and often 2-5 mm, while the thickness of the passage walls is normally less than 1 mm.

Abstract: The sealing device is intended for sealing in one direction between the co-operating surface of a cylindric cavity and the shell surface of a spindle (3) movable therein. One or the other surface is provided with an annular groove (9), in which a sealing ring (8) is located, which is slightly movable in axial and radial direction and intended to minimize fluidum leakage in axial direction between the co-operating surfaces. The ring (8) has small cross-sectional dimensions in relations to the spindle (3) and enclosing cavity. The ring is slim but is of rigid material. The sealing surface (12) of the ring is slightly conic. The ring abuts on the radial inner surface (11) of the groove along a supporting surface, which is annular and has a substantially smaller height than the cross-sectional height of the ring and is located adjacent the sealing surface. One or more grooves are located in peripheral direction about the inner surface of the ring.
