Embodiment Construction

[0022] The profile rail guide according to the invention embodied in FIGS. 1 to 4 comprises a guide trolley 1 which is hydrostatically mounted on a guide rail 2 . The guide rail 2 has a head part facing the guide trolley 1 and a foot part facing a machine part (not shown here) on which the guide rail 2 is fastened. The guide rail 2 is provided on its head part with a center surface 3 along the longitudinal axis of its profile rail guide. The guide rail 2 is provided with a plurality of through-holes 4 arranged along the guide rail, through which fastening screws shown here pass for fastening the guide rail to the above-mentioned machine part. The through-hole 4 penetrates through the center surface 3 of the guide rail 2 .

[0023] On its head part, the guide rail 2 is provided with two upper bearing surfaces 5 and two lower bearing surfaces 6 . The upper support surfaces 5 are planar and are arranged obliquely relative to the center surface 3 , with one upper support surface...

Abstract

The invention relates to a flow control valve (11) for a hydraulic line comprising an outlet (18a) for hydraulic fluid, an inlet (18) for hydraulic fluid and a differential pressure controller (17) for a constant volume flow of the hydraulic fluid which is independent of pressure, and a control part (15a) for adjusting the control behaviour of the differential pressure controller (17). The control part (15a) comprises an operating section (27) for controlling the control part (15a), said operating section being provided such that it is accessible from the outside of the hydraulic line.

Description

technical field [0001] The invention relates to a flow regulating valve for a hydraulic pipeline. [0002] A flow regulating valve connected to the hydraulic line controls the flow of hydraulic fluid through the hydraulic line, wherein the control characteristic of the flow regulating valve is more or less independent of the viscosity of the hydraulic fluid and the pressure at the inlet of the pressure regulating valve. The invention also relates to a hydraulic system in which such a flow control valve is provided. The invention relates in particular to a hydrostatic profile rail guide in which a flow control valve of this type is used. Background technique [0003] Two-way flow regulating valves according to DIN ISO 1219 are known from the company Hydac International for oil hydraulic systems, which keep the outgoing volume flow constant by means of a control process. The volume flow is as independent as possible of pressure and viscosity. The magnitude of the volume flo...
