| The invention concerns a braking system (10) comprising at least one brake circuit (I) in which a high-pressure pump (20) is disposed. A self-priming charge pump (36) is also provided and is connected by an intake pipe (39) to a brake fluid supply container (12) and by a pressure pipe (41) at least indirectly to the intake side of the high-pressure pump (20). When the brake fluid supply to the charge pump (36) is defective, no air should be fed to the brake circuit (I). To this end, the intake pipe (39) of the charge pump (36) comprises a siphon (40; 54-56). Air drawn in through the siphon (40; 54-56) stops the feed to the charge pump (36) in an abrupt manner. The braking system (10) is intended for use in motor vehicles with slip control or for automatic braking. | ||||||

A positive displacement pump 10 includes a pressure chamber 62 having a pumping outlet 79 connected to a delivery conduit 58. The pump 10 includes a bypass outlet 64 connected to the pressure chamber and a valve 70 in the bypass outlet. The valve 70 is open when the pump is not operative and closes automatically when a predetermined pumping volume is attained. The pump may advantageously be a submersible progressive cavity pump, the delivery conduit being a rising main having a foot valve 80 associated therewith. The bypass outlet is in communication with a body of fluid external of the rising main, eg with a borehole. Initially, during start-up, delivery of the pump is directed via the bypass outlet against a low head or substantially no head. Only after start-up, is the delivery directed via the pumping outlet 79, into the delivery conduit at a head prevailing in the rising main 58. |

| 12 | Portable, rotary vane vacuum pump with automatic vacuum breaking arrangement | US12691457 | 2010-01-21 | US09080569B2 | 2015-07-14 | Gregory S. Sundheim |
| A portable, rotary vane vacuum pump with an automatic vacuum breaking arrangement that vents the pump to atmosphere whenever the drive motor ceases to rotate the pump. The arrangement prevents lubricating oil in any substantial amount from being undesirably drawn into the evacuated pump when the drive motor is shut off either intentionally or unintentionally. If the system being evacuated is also still connected to the pump, the arrangement will additionally vent it and greatly limit any amount of oil that may be undesirably sucked back into it. The pump further has a primary oil container that essentially holds all of the oil for the system. The primary container is preferably made of clear, rigid plastic and is also removable from the main body of the pump so it can be quickly and easily replaced with another container of fresh oil even while the pump is still operating. | ||||||

| The brake system has at least one brake circuit (I), in which a high-pressure pump is disposed. A self-aspirating charge pump is also provided, which is connected at least indirectly to the intake side of the high-pressure pump by an intake line of a supply container for brake fluid and by a pressure line. In the event of an inadequate supply of brake fluid by the charge pump, the pumping of air into the brake circuit (I) is intended to be precluded. To that end, a siphon is disposed in the intake line of the charge pump. Air aspirated by the siphon suddenly prevents pumping by the charge pump. The brake system is intended for use in motor vehicles with slip control or for automatic brakes. | ||||||
| 15 | Oil distribution gear pumps with integrated air separators | US4085 | 1993-01-13 | US5266011A | 1993-11-30 | Daewon Son |
| An oil distribution gear pump with an integrate air pump. This pump comprises a main body being divided into an oil distribution chamber and an oil recirculation chamber, these chambers being adapted for distributing oil to the outside and recovering oil from oil bubbles, respectively, and communicating with each other through a bubble circulation conduit and an oil recovering port. The eccentric rotary gear assembly for sucking up oil and feeding the oil to the oil distribution chamber includes a drive gear internally engaging with an eccentric rotary gear. This gear assembly is elastically supported by a compression coil spring such that the drive gear elastically advances and retracts when the eccentric rotary gear eccentrically rotates. The first and second floats are arranged in the oil distribution chamber and the oil recirculation chamber for closing or opening the bubble circulation conduit and the oil recovering port, respectively. The bubble circulation conduit is connected to an air separator for separating air from oil bubbles and ejecting the oil bubbles to the inside of the oil recirculation chamber in order to burst these bubbles. The separated air is discharged to the outside, while the remaining oil is recovered by the oil distribution chamber. | ||||||
| 16 | Fuel pump with a vapor vent valve | US520553 | 1990-05-08 | US5039284A | 1991-08-13 | Edward J. Talaski |
| A positive displacement type pump for use in a fuel system of an internal combustion engine having a pump housing that includes a pump chamber and a vapor vent valve to allow vapor to flow out of the pump chamber. The vent valve includes a valve seat, a valve and a spring biasing the valve away from the valve seat. During pump operation, the liquid fuel flow pressure within the pump chamber is great enough to seat the valve and prevent fuel from escaping through the vapor vent valve. However, if the internal pressure drops due to a loss of pumping pressure caused by the ingestion of air or vapors, the vent valve automatically opens to allow vapor or air flow through the pump with a resultant cooling effect on the pump assembly. | ||||||
| 17 | Oil burner pumping system with air purging valve | US631578 | 1975-11-13 | US4021155A | 1977-05-03 | Robert W. Erikson; Frank L. Harwath |
| A fuel burner pumping system includes a pump having an inlet communicating with a fuel source and an outlet which communicates with a control valve assembly for regulating the pressure of the fuel supplied to the fuel burner nozzle or nozzles through a nozzle passage leading from an outlet port of a main chamber in the control valve assembly. High pressure fuel is pumped into the main chamber through a first outlet passage leading from the pump. A second outlet passage leading from the pump to the nozzle passage by-passes the control valve assembly so that air may be purged from the system when the pump initially is started. An air purging valve within the second outlet passage is movable between closed and open positions for blocking fuel flow through such passage during normal operation of the pump and for opening the second passage when the pump initially is started. In one form of the invention, the purging valve is operable manually and, in another form of the invention, the air purging valve operates automatically. | ||||||

| The invention relates to a pumping device comprising a pump driven by a motor, a diaphragm which is subjected to the water pressure downstream of the pump and a contactor which is actuated by the diaphragm for the purpose of controlling the motor. The pump is of the gear type and a check-valve is placed upstream of the diaphragm in the distribution line which is supplied by the pump. The invention is of particular interest for the supply of water to caravans, bungalows or like premises.
