Construction design of an axial piston pump , in which the swash plate and the control disc are firmly connected to the drive shaft and rotate with it, while the cylinder block, which is firmly connected

Hydraulic pump — mostly with a single piston — for manual operation. It is single-acting in most cases, i.e. priming occurs during the first section of the cycle and delivery during the second. With d

pressure ( Figure P 36 ). If large flows need to be controlled, a multi-pump system may be more cost-effective, consisting of one variable pump and several constant pumps , which can then be connected as desired [...] desired ( Figure P 37 ). As larger masses are to be moved in the pump with the pump control than in the case of the control with throttle, the dynamic behaviour attainable is lower: Frequencies of between

the oil automatically. This suction capacity is highly dependent on the construction design of the pump, its geometric displacement and rotation speed (large pumps must run slower to still be able to suck

Pump where the increase in energy associated with a medium is largely dependent on the kinetic energy applied to it. For flow rate and pressure , it is a case of: where D = profile diameter, u = circu

High volume low-pressure pump (mostly gear pump) for obtaining a high rapid traverse speed. It is shut down as soon as the pressure set on its idle circulation valve is reached.

Time that a variable pump requires to adjust from zero to max. delivery flow (regulated). It depends on the adjustment mechanism, the pilot pressure and the adjustment travel, and also on the mass that [...] pumps and radial piston pumps generally provide good adjustment characteristics. The axial piston pump of inclined axis design has the largest mass to move.

Valve that switches the pump to a pressure-free circulation as soon as its flow rate is no longer needed in the circuit. Special 2/2 directional valves or pressure valves are suitable for use as a shut-off

Hydraulic pump , consisting of several single pumps working in series. The aim is to achieve a higher pressure than permitted by the single pump. Sample application: Internal gear pump , which reaches
