Abstract
A housing for a lubricant supply device for supplying a consumer with a lubricant includes a storage space for the viscous medium and a pump space configured to contain a conveying pump for pumping the viscous medium from the storage space to a medium outlet. The storage space is at least partially defined by a side wall, a base wall and a cover wall, and the supply device also includes an outer wall overlying a portion of the storage space side wall and defining with the storage space side wall a first intermediate space. The storage space side wall includes a first opening providing fluid communication between the storage space and the intermediate space.

A housing for a lubricant supply device for supplying a consumer with a lubricant, the housing comprising:
- a storage space for the lubricant;
- and,
- a pump space configured to contain a conveying pump for pumping the lubricant from the storage space to a medium outlet,
- wherein the storage space is at least partially defined by an inner surface of a side wall, a base wall and a cover wall,
- wherein the housing includes an outer wall overlying a portion of an outer surface of the storage space side wall and defining with the outer surface of the storage space side wall a first intermediate space, and
- wherein the storage space side wall includes a passage from the inner surface of the side wall to the outer surface of the side wall providing fluid communication between the storage space and the first intermediate space.
A housing for a lubricant supply device for supplying a consumer with a lubricant, the housing comprising:

- a pump space configured to contain a conveying pump for pumping the lubricant from the storage space to a medium outlet,
- wherein the storage space is at least partially defined by a side wall, a base wall and a cover wall,
- wherein the housing includes an outer wall overlying a portion of the storage space side wall and defining with the storage space side wall a first intermediate space,
- wherein the storage space side wall includes a first opening providing fluid communication between the storage space and the first intermediate space,
- wherein the pump space is at least partially defined by a side wall, a base wall and a cover wall,
- including an outer wall overlying a portion of the pump space side wall and defining with the pump space side wall a second intermediate space, and
- wherein the pump space and the storage space are disposed with respect to each other such that the first intermediate space and the second intermediate space are in fluid communication with one another.
A housing for a lubricant supply device for supplying a consumer with a lubricant, the housing comprising:
- a cylindrical side wall surrounding a storage space and a pump space, the side wall having an inner surface, an outer surface, a top end and a bottom end,
- a cover at the top end,
- a base wall at the bottom end,
- an outer wall overlying a portion of the outer surface of the side wall and radially spaced from the outer surface of the side wall and defining with the outer surface of the side wall an intermediate space,
- a passage in the side wall extending from the inner surface of the side wall to the outer surface of the side wall and fluidically connecting the storage space to the intermediate space, and
- an opening connecting the intermediate space to an environment outside the lubricant supply device,
- wherein the cover overlies a top end of the intermediate space and the base wall lies under a bottom end of the intermediate space.
