Abstract
A vehicle hydraulic oil reservoir assembly includes a main reservoir and an auxiliary reservoir. The main reservoir has a lower portion and an upper portion. The auxiliary reservoir has a lower portion and an upper portion. The auxiliary reservoir has a port formed in the upper portion thereof. The lower portion of the auxiliary reservoir is communicated with the lower portion of the main reservoir. A breather vent is in communication with atmosphere. A vent pipe communicates the port with the breather vent.
Claims9
A reservoir assembly comprising:
- a main reservoir having a lower portion and an upper portion, the main reservoir having a main port formed in the upper portion thereof;
- a main vent conduit having a first end which communicates the main port, the main vent conduit extending away from the first end, the main vent conduit having a first resistance to air flow therethrough;
- an auxiliary reservoir having a lower portion and an upper portion, the auxiliary reservoir having an auxiliary port formed in the upper portion thereof, the lower portion of the auxiliary reservoir being communicated with the lower portion of the main reservoir;
- a breather vent which is in communication with atmosphere;
- and
- a vent pipe which communicates the auxiliary port with the breather vent, the vent pipe having a second resistance to air flow therethrough, the first resistance being greater than the second resistance so that fluid will release faster from the auxiliary reservoir than from the main reservoir.
A vehicle hydraulic oil reservoir assembly, comprising:
- a main reservoir having a main port formed in an upper portion thereof;
- a main vent conduit having a first end which communicates the main port, the main vent conduit extending away from the first end, the main vent conduit having a first resistance to air flow therethrough;
- an auxiliary reservoir having a lower portion and an upper portion, the auxiliary reservoir having an auxiliary port formed in the upper portion thereof, the lower portion of the auxiliary reservoir being communicated with a lower portion of the main reservoir;
- a breather vent which is in communication with atmosphere;
- and
- a vent pipe which communicates the auxiliary port with the breather vent, the vent conduit being longer than the vent pipe so that resistance to air flow through the vent conduit is greater than resistance to air flow through the vent pipe, and so that oil will release faster from the auxiliary reservoir than from the main reservoir.
A vehicle hydraulic oil reservoir assembly, comprising:
- a differential housing enclosing a main reservoir, the main reservoir having a main port formed in an upper portion thereof;
- a main vent conduit having a first end which is communicated with the main port, the main vent conduit extending away from the first end, the main vent conduit having a first resistance to air flow therethrough;
- an auxiliary reservoir, the auxiliary reservoir having an auxiliary port formed in an upper portion thereof;
- a passage communicating the auxiliary reservoir with the main reservoir;
- a breather vent which is in communication with atmosphere;
- and
- a vent pipe which communicates the auxiliary port with the breather vent, the vent conduit being longer than the vent pipe so that resistance to air flow through the vent conduit is greater than resistance to air flow through the vent pipe, and so that oil will release faster from the auxiliary reservoir than from the main reservoir.
A vehicle hydraulic oil reservoir assembly, comprising:
- a differential housing enclosing a main reservoir, the main reservoir having a lower portion and an upper portion;
- a first auxiliary reservoir having a lower portion and an upper portion, the first auxiliary reservoir having a first port formed in the upper portion thereof, the lower portion of the first auxiliary reservoir being communicated with the lower portion of the main reservoir;
- a further auxiliary reservoir having a lower portion and an upper portion, the further auxiliary reservoir having a further port formed in the upper portion thereof, the lower portion of the further auxiliary reservoir being communicated with the lower portion of the main reservoir;
- a first breather vent which is in communication with atmosphere;
- a first vent pipe which communicates the first port with the breather vent;
- a further breather vent which is in communication with atmosphere;
- and
- a further vent pipe which communicates the further port with the further breather vent.
