<p>The valve is for shock-free decompression for hydraulic systems. A pressure piston of a working cylinder can be moved in an operating path and a rapid path. After reaching the maximum pressure (final working pressure), a decompression valve (7) fitted with a choke (14) can be controlled via pressure switch. After a partial pressure drop in the working cylinder, a suction valve opens. The effective cross-section of the choke (14) of the decompression valve (7) can be varied according to the pressure in the working cylinder. Thus, this choke cross-section is greater at lower pressure than at higher pressure. The decompression valve (7) has control slide (10) which can move against a spring (11), by means of which the effective choke cross-section is controlled.</p> |
