Abstract
The present invention relates to a reciprocating pump in which a plunger is reciprocated by means of a crankshaft, a connecting rod and a crosshead. The reciprocating pump further includes cushioning means which is disposed between the crosshead and the plunger and capable of adjusting its cushioning force and absorbing the plunger stroke, whereby the delivery pressure is adjustable through adjustment of the cushioning force of the cushioning means and the delivery volume or rate is also adjustable through absorption of the plunger stroke by the cushioning means.
