Definitions
- the invention relates to a dry running vane gas pump.
- Such vane-type gas pumps are known from the prior art and are usually used in motor vehicles as so-called vacuum pumps in combination with a brake booster.
- the vane pump delivers the time required for the operation of the brake booster negative pressure, which is absolute 100 mbar or less in the rule.
- the vane-cell gas pumps known from the prior art are usually dry-running or oil-lubricated vane-cell gas pumps, wherein in the case of dry-running gas pumps, no lubricant is conducted into the pumping chamber.
- oil-lubricated vane pumps the air exiting the pumping chamber is mixed with lubricant, and prior to disposal of this air-lubricant mixture, the air-lubricant mixture must be laboriously separated into its components.
- By omitting the lubricant the contamination of the air leaving the pumping chamber can be avoided.
- the omission of the lubricant but leads to increased wear of the relatively moving components, in particular the slide elements. The wear is usually reduced to a minimum by selective choice of suitable material pairings of the abutting and mutually relatively moving components.
- Such a dry-running vane-cell gas pump is disclosed in EP 2 568 180 A1.
- the vane pump has a pump housing on, which forms a pumping chamber.
- a pump rotor is arranged, which has five radially displaceable slide elements.
- the pump rotor is rotatably connected to an electric motor and is driven by this.
- the slide elements move due to the force acting on the slide elements centrifugal force such that they rest with their head each on a peripheral wall of the pumping chamber, each two adjacent slide elements together with the pump rotor and the pump housing each define a Pumpfach.
- a fluid inlet opening and two fluid outlet openings are formed, wherein the fluid inlet opening and the fluid outlet openings are associated with the pumping chamber. Both fluid outlet openings each have a check valve, so that the fluid outlet openings are released only from a prevailing in the Pumpfach predefined overpressure.
- the invention is therefore based on the object to avoid the above drawback.
- the dry-running gas pump has a pump housing, which limits a pumping chamber.
- a pump rotor is arranged, which is driven either electrically by an electric motor or mechanically by an internal combustion engine.
- the pump rotor is arranged eccentrically in the pumping chamber and abuts in a sealing sector on the peripheral wall of the pumping chamber, whereby a sickle-shaped working space is created.
- the pumping chamber is divided into function in an inlet, an outlet and a sealing sector.
- a fluid inlet opening is arranged, which is fluidically connected, for example, with a vacuum chamber of a brake booster.
- a first fluid outlet opening and a second fluid outlet opening are arranged, wherein the pumping chamber can be connected to the environment via the fluid outlet openings.
- the sealing sector is arranged, which prevents a gas flow between the fluid inlet opening and the fluid outlet openings.
- the first fluid outlet opening is arranged in the direction of rotation of the pump rotor in front of the second fluid outlet opening, wherein the first fluid outlet opening is associated with a check valve.
- the check valve closes the first fluid outlet opening and releases it from a predefined positive pressure prevailing in the pump chamber.
- the second fluid outlet opening does not have a check valve, so that the second fluid outlet opening is permanently open.
- At least two slide elements are mounted in the pump rotor, whereby the hydraulic efficiency of the vane pump is increased by the leakage between the pressure side and the suction side is significantly reduced with increasing number of slide elements.
- the angular distance between the first fluid outlet opening and the second fluid outlet opening is smaller as the Pumpachwinkel.
- the angular separation is defined as the angular separation between the trailing edge of the first fluid outlet port and the leading edge of the second fluid outlet port.
- the pump tail angle is defined by two adjacent slide elements. Characterized in that the angular distance between the first and the second fluid outlet opening is smaller than the Pumpfachwinkel, the Pumpfach is fluidly connected in the outlet sector at any time with at least one fluid outlet opening. In this way, a build-up of pressure in the Pumpfach is avoided, which would occur if the Pumpfach in the outlet sector would not be fluidly connected to any of the two Fluidauslassö réelleen, and the ejected air could not escape. As a result, the mechanical tangential load is reduced to the slider element.
- the tangential width Bl of the at least one slide element preferably corresponds at least to the tangential width B2 of the first fluid outlet opening, whereby the second fluid outlet opening is completely covered and briefly closed when passing through the at least one slide element.
- the pump housing has a valve cover, a lifting ring and a bottom cover.
- the cam ring forms the peripheral surface of the pumping chamber and lies with its end face on the valve cover and with its other end face to the bottom cover sealingly.
- the valve cover closes off the pumping chamber on one side and has the at least two fluid outlet openings.
- the bottom element has the fluid inlet opening.
- FIG. 1 shows a vane-cell gas pump 10 designed as a so-called vacuum pump, which is intended, for example, for use in a motor vehicle and can generate an absolute pressure of, for example, 100 mbar or less.
- the vane pump 10 has a metal pump housing 20, which forms a pumping chamber 22.
- the pump housing 20 is essentially composed of a lifting ring 74, a bottom plate 76 and a valve cover 72.
- the fluid inlet port 60 is formed in the bottom plate 76.
- the two fluid outlet openings 52, 54 are formed in the valve cover 72.
- the first fluid outlet opening 52 is arranged in the direction of rotation of the pump rotor 30 in front of the second fluid outlet opening 54.
- the first fluid outlet 52 is fluidly associated with a check valve 70, wherein the check valve 70 is a reed valve and a valve tongue 80 and a Wegbegrenzer 82, both of which are fixed to the valve cover 72.
- the second fluid outlet opening 54 is not associated with a valve, so that the second fluid outlet opening 54 is permanently open and allows a resistance-free fluid flow.
- the second fluid outlet opening 54 is spaced at an angular distance b from the first fluid outlet opening 52, wherein the angular distance b between a leading edge of the second fluid outlet opening 54 and the trailing edge of the first fluid outlet opening 52 is measured.
- the angular distance b is smaller than one through two adjacent pusher elements 32, 34, 36, 38, 40 trapped Pumpfachwinkel a, so that the exhaust sector 44 passing through Pumpfach is always fluidly connected to at least one fluid outlet opening 52, 54.
