Filed: 1988-08-09
Abstract: Compressed air dryer having a flow duct which is completely provided, at least in sections, with a porous component which can be flowed through. The articles can be joined to one another and to the boundary of the flow duct or of the heat exchanger wall by adhesion (bonding) or by sintering. The porous component, which can be flowed through, can act simultaneously as a filter. It is possible to connect downstream of the compressed air dryer a heat store (accumulator) which can be thermally discharged by the refrigerating (cooling, cold-producing) machine in the case of part-load operation on the compressed air side, and is provided with a heat exchanger surface to the compressed air, which corresponds to the recuperator output or leads to the desired escape temperatures of the compressed air. It is thereby possible to design the refrigerating machine for an output which corresponds to the non-recuperable output in the case of full-load operation.

Title: Hydraulic directional control valve
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B13/04
Filed: 1988-10-05
Abstract: A hydraulic directional control valve (10) for control independent of load pressure is proposed which is suitable for use as a left-hand and right-hand type in control valve blocks and for the installation of auxiliary functions. A measuring-choke point (17) formed with two measuring-choke chambers (15, 16) lies in the centre of the housing (12). The working chambers (19 to 25) and the allocated control edges (49, 52, 54, 56) at the control spool (14) are arranged symmetrically to the measuring-choke point (17). Each feed chamber (19, 23) is protected by a non-return valve (31, 32), where a pressure tap (34), lying between the non-return valves, of a load-pressure selecting device (35) can be relieved by the control spool (14) in its centre position via a relief bore (58) to the return passage (45). By fitting the control spool (14) in the housing (12) in a position rotated through 180@ to its transverse axis, a right-hand type can be produced from the left-hand type shown in Figure 1 while the load-pressure selecting device (35) stays the same. <IMAGE>
