Reservoirs

 

Two types of reservoirs are present: atmospheric and pressurised.

The atmospheric reservoir has the following inputs and output:

Return flows from the systems (is a vector) [m3/s]

Pump flow [m3/s]

Relief valve flow [m3/s]

Single Acting Actuators flow of the uncontrolled pressure side

Reservoir volume [cc] The parameter to be defined is the initial volume of the fluid inside the reservoir

 

The pressurised reservoir block has the following inputs and output:

Return flows from the systems (is a vector) [m3/s]

Pump flow [m3/s]

Relief valve flow [m3/s]

Pressures [Pa] (the output of the Accumulator block)

Single Acting Actuators flow of the uncontrolled pressure side

Reservoir volume [cc] - Return pressure ('GoTo' block)

 

The flow coming from the single acting actuators shall be connected only if the pressure of the side not controlled by the valve is the return pressure, otherwise this input shall be connected to a ground block (from Utility sub-library).

The schematic of a pressurised reservoir is shown in the following figure:

 

The reservoir pressure (Pr) acts on the area (A1 + A2 - A3), while the system supply pressure (Ps) acts on the areas (A2 - A3).
