Swash plate machine
Axial piston machine ( Axial piston pump or Hydraulic motor ) with a rotating cylinder block in which the piston strokes are caused by a fixed swash plate with a largely adjustable drive angle (max. a
Paraffin base oil
The base oil is of the paraffin variety. Paraffin base oils have a low aromatic content; they are associated with good lubricating performance and favour high loads during continuous operation. They o
Constant pressure system
System in which the pressure at the hydraulic pump remains constant regardless of the flow rate and how high the load pressure is. Strictly speaking, this is only really the case with: controls with t
Programmable control
memory programmable control with random access memory (RAM) as program memory ( semiconductor memory ) the entire contents of which can be changed, even only slightly, without mechanical intervention
Swivel motor
Device for turning movements (swivelling) at a limited angle (approx. 60° up to a maximum of 360°). A distinction is made between ( Figure S 41 ): The most simple construction type, which requires the
Two edge control
1. Hydraulic resistance control for a displacement chamber with a type A hydraulic half bridge (adjustable input and output resistance); use of both control edges of a continuously adjustable 3/2-way
Charge pump
The most common application of a charge pump in hydraulic systems is "charging" a pump in the open circuit (due to improved filling in the priming phase, it can be run at a higher rotation speed) and
Proportional amplifier
Electronic control amplifier for proportional valves ; often installed on a European circuit board . A specific electronic amplifier card is allocated to a specific type of proportional device: valves
Circular sealing gap
Axial circular sealing gap : Gap created when a piston runs inside a bore (e.g. pump pistons, valve control spools in valves). Providing a centric gap is involved, the leakage will depend on the follo
