Title:
ポンプ改良物
Document Type and Number:
Japanese Patent JP5504251
Kind Code:
B2
Abstract:
A pump that has a flangeless valve plate, meaning that the valve plate has no flange through which bolts that secure the head to the pump extend. The pump has eccentrics and pistons that all have holes in them so that the pistons at opposite ends of the pump can be assembled to the shaft of the motor 180° out of phase. The pump further has a monolithic head that includes the two head members of the pump and the tube that connects them also has an integrally formed port. The pump is supported by elastomeric tubular members from its ports. The pump has a push-in fitting that can be pushed into a hole in a member such as the head, the housing or the base so that once pushed in, a ring around the fitting expands outwardly behind an edge of the body to trap the fitting in the opening.
