20170052549 · 2017-02-23 ·

Embodiments of the invention provide a relief valve body arranged for connecting to a pressure vessel. The relief valve body includes an inlet configured to connect to a pressure vessel and an integrated nozzle downstream from the inlet and extending along an axis. The integrated nozzle includes a nozzle exterior surface, a nozzle bulb, and a valve seat and defines a nozzle expansion region. The relief valve body further includes a redirecting pallet, a valve interior surface having at least one ramped portion downstream from the integrated nozzle and redirecting pallet, and an outlet downstream from the at least one ramped portion.

Electrohydraulic pilot control with two pressure control valves

Electrohydraulic pilot control means (1) for a hydraulic device which can be a proportional directional valve, an adjusting pump or an adjusting motor, which pilot control means contains two proportionally acting pressure control valves (3) and is provided with a control block (2) which accommodates the hydraulic valve parts (4) in holes and to which the associated proportional magnets are flange-connected, wherein the proportional magnets have a common electrical plug connection (5) and wherein the two proportional magnets (3) are joined to form an assembly by being encapsulated with plastic, the said assembly being fastened to the control block (2) and, in this case, being precisely oriented relative to the valve components (4), which are accommodated in the control block, by means of positioning aids which act perpendicular to the movement direction of armatures.
