CH Schematic Diagrams

I. Hydraulic Actuation Wet or Dry Operation

Schematic # 1: Displays a typical circuit diagram for a hydraulically actuated wet or dry-running disc clutch. The pump (C) draws the oil through the filter (D) from the reservoir (H) and passes it under pressure to the operating pipeline. The operating pressure is adjusted by the limiting valve (E). Any excess oil flows back to the reservoir. The clutch (A) is operated when the “ON” position of the control valve (B) is selected.

B. 3/2 Control Valve
C. Fixed Displacement Pump
D. Filter
E. Pressure Limiting Valve
F. Rotary Connection
G. Non-Return Valve
H. Oil Reservoir

 

 


II. Pneumatic / Air Actuation Dry Operation

Schematic # 2: Displays a typical circuit diagram for a pneumatically actuated, dry clutch. The  accumulator (G), enables fast  actuation, and should be installed  as close as possible to the clutch. The accumulator’s capacity is determined by the volume of the piping, fittings and the cylinderpiston volume of the clutch used in the application.

E. Lubricator
F. Non-Return Valve
G. Accumulator
H. Rotary Connection
I. Shut-off Valve
J. Main Supply

 


III. Hydraulic Actuation Wet operation with through shaft oil lubrication

Schematic # 3: Displays a typical circuit diagram for a hydraulically actuated clutch with through shaft lubrication directed at the disc pack. During engagement, the excess oil flows through a cross drilled port through the shaft of the clutch. The throttle valve (E2) acts as the regulator of coolant flow.

B. 3/2 Control Valve
C. Fixed Displacement Pump
D. Filter

F. Pressure Limiting Valve
G. Non-Return Valve
H. Accumulator
I. Oil Reservoir

 


 

IV. Hydraulic Actuation Wet operation with intensive through shaft oil lubrication


Schematic # 4: Displays a typical circuit diagram for clutches with separate actuation and coolant/lubrication sections. When not engaged, a small amount of coolant flows through the throttle valve (E) to the disc pack. During engagement, the control valves (B & F) are activated at the same time, resulting in a large volume of coolant is introduced. The coolant flows through the 2/2 control valve (F) directly to the disc pack.

A. Clutch
B. 3/2 Control Valve
C. Fixed Displacement Pump
D. Filter
E. Throttle Valve
F. 2/2 Control Valve
G. Pressure Limiting Valve
H. Oil Reservoir
