Volume flow rate smoothing device

A volume flow rate smoothing assembly comprising:

• a volume flow rate smoothing device comprising:
• a body portion defining a chamber therein, wherein the body portion includes a bulbous expansion body and a flow body connected to the bulbous expansion body, and wherein the chamber is defined by the flow body and the bulbous expansion body;
• a first flow restrictor portion and a second flow restrictor portion each disposed in fluid communication with the body portion,
• wherein:
• the volume flow rate smoothing device is configured to fluidically communicate with a pump via a first end of the volume flow rate smoothing device to receive a fluid flow from the pump along a fluid pathway extending through the first flow restrictor portion, the body portion, and the second flow restrictor portion,
• the first flow restrictor portion is disposed upstream of the body portion, and
• the second flow restrictor portion is disposed downstream of the body portion;
• a first flow tube configured to operably connect to the first end of the volume flow rate smoothing device downstream of the pump;
• and
• a second flow tube configured to operably connect to a second end of the volume flow rate smoothing device downstream of the second flow restrictor portion.
