Abstract
The utility model discloses an oil/gas separator, including the casing that has an inner chamber, be provided with the carbon tank interface on the casing, oil filler hole interface and oil gas input interface, be provided with the oil gas input channel of inner chamber intercommunication in the oil gas input interface, be provided with the filtering component that is rebuffed in the inner chamber, rebuffed filtering component includes the baffle assembly who separates into the inner chamber upper plenum and lower cavity, baffle assembly is provided with inlet channel, carbon tank interface and upper plenum intercommunication, oil filler hole and upper plenum intercommunication, its advantage is that oil gas enters into the inner chamber from input channel, baffle assembly is met earlier to oil gas, oil gas partly is condensed into the liquid fuel and is flow back in the fuel tank again after rebuffed, the atmosphere pollution is reduced.
Description
Technical field
The utility model relates to a kind of deaerator be arranged in vehicle fuel tank, especially relate to a kind of refuel limitation cut-off valve deaerator.
Background technique
Vehicle fuel tank is provided with overflow cutting valve usually, there is following effect: 1) during vehicle fuel tank oiling, make vehicle fuel tank and air have certain passage by overflow cutting valve; And after vehicle fuel tank fills fuel oil, overflow cutting valve can be closed automatically, prevent fuel oil from overflowing from overflow cutting valve.2) last importantly when the position of fuel tank changes suddenly (as vehicle rollover), overflow cutting valve can stop fuel oil to flow out.Authorize on September 14th, 2011 patent No. announced be 201120078737.7 name be called " a kind of overflow cutting valve; it discloses valve casing upper end and be provided with inlet hole; the valve that can fluctuate in valve casing is set in valve casing and floats core; valve floats on core and is provided with fixing button; fixing button is provided with rubber valve; be close to as skin valve the upper surface that valve floats core, and valve floats between core and valve bottom and is provided with spring.In the normal oiling of fuel tank or with in oily process, valve floats core and falls back to valve bottom, and spring is in compressive state, form air-flow path in valve body, make fuel tank keep normal air pressure.When in fuel tank, fuel oil is filled it up with, valve floats the floating function float downward of core at fuel oil, and the lower end of inlet hole is blocked by rubber valve, and fuel oil can be prevented from vent to outflow.The valve mouth of pipe of this overflow cutting valve is connected with canister.The oil gas major part that fuel tank is distributed by overflow cutting valve enters into canister, again enters air after being filtered by canister.
ORVR (OnboardRefuelingVaporRecovery) i.e. vehicle-mounted oil filling gas recovery system for oil, be a kind of vehicle emission control system, it can collect the fuel vapor evaporated from fuel tank in refueling process.This technology is that U.S. EPA was released in 1994 using a kind of alternative as secondary gas recovery system for oil.In this oiling gas recovery system for oil, fuel tanks of automobile is installed an oiling limitation cut-off valve, comprise a valve body and deaerator, the Single port of deaerator is communicated with oiling port, and the another port of deaerator is communicated with canister.The function of this oiling limitation cut-off valve is: must seal when overturning, close after must reopen, dynamic leakage must be little, stops that liquid infiltrates in canister, oil level is closed highly accurate, bear the oil gas distributed simultaneously and all enter canister and filter.The complex structure of traditional oils gas separating device, oil gas separation is bad simultaneously.
Model utility content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the deaerator of good oil gas separation effect.
This deaerator belongs to a part for oiling limitation cut-off valve, is separated by the oil gas run out of, the fuel oil after isolating is back in fuel tank again, reduces the pollution to air in fuel tank.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of deaerator, comprise the housing with an inner chamber, described housing is provided with canister interface, oil filler interface and oil gas input interface, the oil gas input channel of inner space is provided with in described oil gas input interface, rebuffed filter assemblies is provided with in described inner chamber, described rebuffed filter assemblies comprises baffle assembly inner chamber being separated into upper plenum and lower cavity, described baffle assembly is provided with gas-entered passageway, described canister interface is communicated with described upper plenum, described oil filler is communicated with described upper plenum.
The further preferred version of the utility model is: described baffle assembly comprises two pieces of symmetrical swash plates, and gas-entered passageway is opened in the intermediate portion that two pieces of swash plates combine.
The further preferred version of the utility model is: be provided with the tubular body with canister orifice in described upper plenum,
Described upper plenum upper end is provided with U-shaped frame, and the bottom of described U-shaped frame is provided with the vent with tubular body inner space.
The further preferred version of the utility model is: the base plate of described tubular body is provided with the return port communicated with upper plenum.
The base plate of described U-shaped frame is skewed, is conducive to the fuel flow returns after condensing to fuel tank.
Compared with prior art, the utility model has the advantages that oil gas enters into inner chamber from input channel, oil gas first encounters baffle assembly, and a part for oil gas condenses into liquid fuel and is back in fuel tank again after being rebuffed, and decreases the pollution to air.Being provided with of gradient is beneficial to oil gas postprecipitation of being rebuffed and is back in fuel tank.U-shaped frame can carry out being rebuffed to oil gas further and be separated, and the oil gas simultaneously in pipeline is back in fuel tank by return port.
