Low silhouette power steering fluid reservoir

A reservoir of power steering fluid, comprising:

• an upright housing having a vertical axis;
• said housing comprising upper and lower housing sections having mating annular edges joined together along an interface;
• said upper housing section forming an upper interior space adapted to store a reserve supply of power steering fluid;
• said lower housing section comprising a stepped wall structure that includes a first circular side wall extending downwardly from said interface, and a second circular side wall located below said first side wall;
• said second side wall having a smaller diameter than said first side wall so that an annular ledge is formed at the juncture between said first and second circular side walls;
• a fluid inlet connection tangent to said first circular side wall for directing fluid from a power steering unit into said lower housing section;
• a fluid outlet connection tangent to said second circular side wall for directing fluid from the lower housing section to a pump that supplies fluid to the power steering unit;
• and a disk-like filtration means seated on said annular ledge for removing contaminants from the fluid flowing said inlet connection to said outlet connection.
