Abstract
An engine mounting base (8) has a first hollow frame portion (34) containing fluid at generally atmospheric pressure, and a second hollow frame portion (36) containing fluid at a preselected pressure above atmospheric pressure. Preferably, the mounting base (8) includes a plurality of elongate tubes (46,48,50,52,56,60,62,64,76) having closed ends and connected together at various elevations to provide a plurality of chambers (54,58,66,77) useful for fluid distribution and collection purposes.
Claims18
An engine mounting base (8) comprising:
- first hollow frame means (34) for containing a preselected quantity of a fluid at generally atmospheric pressure;
- second hollow frame means (36) for containing another preselected quantity of said fluid at a preselected pressure level above atmospheric pressure, said first and second hollow frame means (34,36) being connected;
- and
- means (40) for containing another preselected quantity of said fluid at an intermediate pressure between atmospheric pressure and said preselected pressure in said second hollow frame means (36).
An engine mounting base (8) comprising:
- first hollow frame means (34) for containing a preselected quantity of a fluid at generally atmospheric pressure;
- second hollow frame means (36) for containing another preselected quantity of said fluid at a preselected pressure level above atmospheric pressure, said second hollow frame means (36) being connected to and at an elevation greater than said first hollow frame means (34);
- pump means (18,20) for communicating said fluid from said first hollow frame means (34) to said second hollow frame means (36);
- and
- means (40) for containing another preselected quantity of said fluid at an intermediate pressure between atmospheric pressure and said preselected pressure in said second hollow frame means (36).
An engine mounting base (8) comprising:
- first hollow frame means (34) for containing a preselected quantity of a fluid at generally atmospheric pressure, said first hollow frame means (34) including first and second substantially parallel elongate tubes (46,48) having closed ends and a third tube (50) connected to said pair of tubes (46,48) and defining a common fluid chamber (54) therewith;
- and
- second hollow frame means (36) for containing another preselected quantity of said fluid at a preselected pressure level above atmospheric pressure, said first and second hollow frame means (34,36) being connected.
In an engine mounting base (8) of the type for supporting an engine (12) having a pump (18) and fluid inlet and outlet passages (22,24) communicating with said pump (18), the improvement comprising:
- a plurality of elongate tubes (46,48,50,52) of rectangular cross sectional configuration interconnected generally at a first elevation and defining a first chamber (54);
- and
- another elongate tube (56) of rectangular cross sectional configuration connected at an elevation above and directly to one of said plurality of elongate tubes (46,48,50,52) and defining a second chamber (58), said inlet and outlet passages (22,24) of said pump (18) being in fluid communication with said first and second chambers (54,58), respectively.
An engine mounting apparatus (8) for supporting an engine (12), comprising:
- a first elongate tube (46) defining a fluid reservoir chamber (54);
- a second elongate tube (56) defining a pressure chamber (58), the first and second elongate tubes (46,56) being connected and rectangular in cross sectional configuration;
- and
- means (18,22,24,94) for communicating fluid from said fluid reservoir chamber (54) at generally atmospheric pressure to said pressure chamber (58) and maintaining a preselected quantity of said fluid at a preselected pressure level above atmospheric pressure thereat.
An engine mounting base (8) for supporting an engine (12), comprising:
- first, second and third tubes (46,48,52) connected together and collectively defining a first chamber (54);
- a fourth tube (56) defining a second chamber (58) and being connected elevationally above and to said first tube (46);
- and
- a fifth tube (62) defining a third chamber (66) and being connected elevationally above and to said third tube (52), each of said tubes (46,48,52,56,62) having a rectangular cross section and being of sufficient strength to provide support for said engine (12).
