In a hydrostatic transmission , the pump can be adjusted and the motor is associated with constant displacement . The drive rotation speed is therefore proportional to the flow rate for the pump, i.e.

Seal type for sealing rotating areas based on a gap seal whereby the gap length is increased by the contour of the gap assuming a meandering or zigzag pattern ( Figure L 1 ). Labyrinth seals — mainly

Basic design for a hydraulic drive in which the fluid circulates from the pump to the actuator and from there straight back into the suction line of the pump. The main difference between this and an "

Pressure at which a filter element becomes so crushed (destroyed) that it ceases to function. According to ISO 2941, however, the collapse pressure is simply the pressure at which the filter element i

Effective element of a limited angle rotary actuator with mostly a rectangular cross-section that is fastened to the shaft and to which a flow of hydraulic fluid is applied.

Noises created when switching and flowing through valves . As opposed to the switching and oscillation noises, the flow noises are the main sources of noise in valves. Oscillation noises primarily ari

Aromatic or paraffinic hydrocarbons in which certain hydrogen atoms are replaced with chlorine. Low flammability is achieved here by means of chlorine (CETOP RP 100). Certain chlorinated hydrocarbons

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 tha

Time from the "on" switching command to the "off" switching command. Of a solenoid : ratio of the switch-on time to the duration of a working cycle in %. The ratio of load to relief time is termed the

Sealing performance of elastic seals that results from the preload during the installation of the seal. It corresponds to the sealing action of the related seal shape at very low pressure. The initial
