Japanese Patent JPH08303354
Kind Code:
A
Abstract:
PURPOSE: To fasten and remove a suction valve and a delivery valve of a plunger pump without any restriction caused by their positions.
CONSTITUTION: A storage chamber 34 of a fastening and removing device 30 is in an airtight state and its bottom part is interposed between a plunger pump 10 and a liquid source 52 so that liquid 54 passes from the liquid source 52 to the suction port 16 of the plunger pump 10. The volume of the storage chamber 34 is decreased by elastic size reduction of a bellows part 36 by application of pressure on a case 32 by pushing force F. A check valve 56 prevents the liquid 54 tram back flowing from the storage chamber 34 to the liquid source 52.
