<p>PROBLEM TO BE SOLVED: To eliminate a process calling for extremely high accuracy to bore a cylinder hole in a pump housing, therefor let manhours required by processing and assembling be saved much, and also let the pump be assembled with ease in such a way that a different capacity can thereby be provided. SOLUTION: A cover 53 is mounted at least to one side of a base stand 51 in liquid tight relation, and a driving mechanism 55 to be driven by driving force provided by the outside of an oil chamber, is housed in and disposed to the oil chamber 57 partitioned by the base stand 51 and the cover 53, the specified number of pump element assemblies 10 which feed fluid in the inside of the oil chamber 57 with pressure at the high speed depending on the action of the driving mechanism 55, are disposed to specified positions in the inside of the oil chamber 57. And furthermore, a planger pump 1 is so constituted that an inflow passage to let fluid flow in the oil chamber 57 and an outflow passage 51a to let force feeding fluid from the pump element assemblies flow out to the out-side, are formed up at the specified positions in the base stand or the cover.</p> |
