Pump pulsation discharge dampener with curved internal baffle and pressure drop feature creating two internal volumes

A hydraulic pulsation control device, comprising:

• an inlet to a body of the hydraulic pulsation control device, the body including an interior chamber;
• an outlet from the body in fluid communication with the interior chamber;
• a baffle within the interior chamber of the hydraulic pulsation control device, the baffle inhibiting direct fluid flow through the body, separating the interior chamber into first and second volumes, and at least partially dampening high frequency pressure pulses within fluid pumped by reciprocating equipment into the first volume of the interior chamber through the inlet and out from the second volume of the interior chamber through the outlet;
• and
• a pressure drop device within a portion of the baffle, the pressure drop device comprising a number of openings each extending through the baffle and distributed at various points on the baffle, wherein the pressure drop device attenuates pressure drops within fluid pumped through the hydraulic pulsation control device,
• wherein a total aggregate diameter for fluid passage through the baffle, including an aggregate fluid passage diameter for the number of openings, is smaller than a diameter for fluid passage for one of the inlet and the outlet.

A hydraulic pulsation control device, comprising:

• an inlet to a body of the hydraulic pulsation control device, the body including an interior chamber, wherein the interior chamber is generally spherical;
• an outlet from the body in fluid communication with the interior chamber;
• a baffle within the interior chamber of the hydraulic pulsation control device, the baffle inhibiting direct fluid flow through the body, separating the interior chamber into first and second volumes, and at least partially dampening high frequency pressure pulses within fluid pumped by reciprocating equipment into the first volume of the interior chamber through the inlet and out from the second volume of the interior chamber through the outlet, wherein the baffle is curved and the body of the hydraulic pulsation control device is spherical;
• and
• a pressure drop device within a portion of the baffle, the pressure drop device having a single fluid passage comprising an annular portion extending into the second volume, wherein the pressure drop device attenuates pressure drops within fluid pumped through the hydraulic pulsation control device,
• wherein a total aggregate diameter for fluid passage through the baffle, including an aggregate fluid passage diameter for the single fluid passage, is smaller than a fluid passage diameter of a fluid passage for the outlet.
