Publication number: 20070237651Abstract: An objective is to provide a reciprocating pump apparatus which can change a position where an adaptor to be fixed to a support is attached, while having a simple form. In a reciprocating pump apparatus 10 having a crankshaft 14 directly connected to an output shaft of a driving source, positions of bolts 22a to 22d for fixing a bearing case 20 for closing an open end part of a crankcase 16 to the crankcase are determined such that an adaptor 40 for fixing the reciprocating pump apparatus to a support 58 is fastened to the crankcase together with the bearing case in a positionally changeable fashion.

Patent number: 5152675Abstract: A single acting, piston type pump comprises a pair of cylinders, and a pair of pistons mounted in respective cylinders for reciprocal movement within the cylinders. The pistons are interconnected with one another so that while one piston is moving upward in its cylinder, the opposing piston is moving downward. An inlet line and an outlet line is connected with the active end of each cylinder for drawing fluid into the active chamber when the piston moves upwardly, and expelling fluid through the outlet line when the piston moves downwardly in the cylinder. A cross-over channel is connected between the passive chambers of the cylinders so that the effective volume of the passive chambers remain constant as the pistons reciprocate within the cylinders. Because the volume of the passive chambers remain unchanged, there is less pressure on the seals surrounding the piston rods and a decreased likelihood of leakage.Type: GrantFiled: June 17, 1991Date of Patent: October 6, 1992Inventor: Billy F.

Patent number: 4776304Abstract: A movement converter for use in a combustion engine or as an air compressor wherein reciprocating motion of a piston is converted to rotational motion of an output shaft or a rotational motion of an input shaft is converted to a reciprocating motion of the piston. The movement converter for use in the engine not only attains an improvement in the balance in comparision with conventional reciprocating type engines but allows the mechanical efficiency to be high enough to be placed into practical use concurrently with its physical dimension being smaller and lighter. The movement converter employs a crosswise disposition of the four cylinders and the interactive use of links together with a Z crank for converting the resulting swinging motion to rotational motion so that all the vibration, including the primary vibration and the secondary vibration, are dissolved by means of an interactive offset.Type: GrantFiled: November 19, 1986Date of Patent: October 11, 1988Inventor: Akira Korosue
