RECIPROCATING PUMP APPARATUS

PROBLEM TO BE SOLVED: To provide a reciprocating pump apparatus which can change a mounting position of an adapter for fixing the pump to a base body, and has a simple shape. SOLUTION: In the reciprocating pump apparatus 10, its crankshaft 14 is directly connected to the output shaft of a driving source. The adapter 40 for fixing the reciprocating pump apparatus to the base body 58 is fixed to a crank case 16 together with a bearing case 20 to close an opened end portion of the crank case 16. In this case, the positions of bolts 22a to 22d for fixing the bearing case to the crank case are determined so as to change the position of the adapter 40. In this configuration, because the position of the adapter can be changed, the degree of freedom of the arrangement layout of the apparatus is improved. Further, because the adapter is mounted using the bolts for fixing a manifold to the crank case, a simple shape can be achieved. COPYRIGHT: (C)2008,JPO&INPIT
