    摘要: A liquid pressure tank is provided for storing liquid under pressure for use in domestic or commercial reticulated supply of the type having an impervious diaphragm dividing the tank into an air chamber and a liquid chamber, a constant amount of air being maintained in the chamber under pressure. A liquid pump and pressure switch system is provided for maintaining liquid in the chamber between preset pressure limits, the diaphragm being so configured and secured to form a pistonlike portion within the tank which reciprocates under variation of liquid pressure to minimize wrinkling or stretching of the diaphragm. Also a fixed plate can be arranged over the liquid outlet as protection from rupturing of the diaphragm at low liquid levels.

    摘要: An accumulator for maintaining a substantially constant pressure above ambient in a hydraulic system including a hollow cylinder which has an opening at one location to ambient and an opening at another location for communication with the hydraulic system; a piston and pushrod disposed in the cylinder for reciprocatory movement between the open locations; and a negator spring which has an arcuate end which is connected to the pushrod and an opposite end which is connected to the cylinder. A rolling diaphragm may be connected to an end of the piston and to the cylinder at a location about the piston wall.

    摘要: A HYDRO-PNEUMATIC PRESSURE RESERVOIR IN WHICH THE HOUSING THEREOF IS PROVIDED WITH AN APERTURE AND A MOVABLE PLIANT WALL OR PARTITION DIVIDES THE INTERIOR OF A HOUSING INTO AN OUTER LIQUID CHAMBER AND AN INNER GAS CHAMBER. THE WALL IS MAINTAINED IN A LIQUID AND GAS TYPE RELATIONSHIP BETWEEN A CLAMPING RING AND A COVER WHICH TIGHTLY SEALS THE APERTURE OF THE HOUSING. THE COVER IS PROVIDED WITH A GAS INLET HOLE HAVING A CLOSURE FOR FILLING THE GAS CHAMBER AS WELL AS A LIQUID CONNECTION WITH THE LIQUID CONNECTION BEING IN COMMUNICATION WITH THE LIQUID CHAMBER VIA CHANNELS IN THE COVER AND PASSAGES BETWEEN THE CLAMPING RING AND THE HOUSING.
