ABSTRACT:
A refuse compactor includes a refuse storage body, a compaction panel movable within the storage body to give refuse within said body an initial pack and a stuffer panel movable within said body to provide the refuse with a secondary pack.
The stuffer panel may apply a higher packing pressure to the refuse than the compaction panel.
The secondary pack applied to refuse by the stuffer panel has an upward component of movement with a greater upward inclination than the packing force applied to the refuse through movement of the compaction panel thereby offsets the gravitational effect of increased densification of refuse in the lower portion of the refuse storage body.
First and second hydraulic motor means are respectively connected to the compaction panel and the stuffer panel. First control means govern the flow of hydraulic fluid to the first motor to provide movement to the compaction panel until the compaction resistance of refuse contacted by the compaction panel raises the pressure of hydraulic fluid within the first motor means to a predetermined level. Second control means control the flow of hydraulic fluid to the second motor means to actuate the stuffer panel when the pressure of hydraulic fluid within the first motor means has reached said predetermined pressure level and to prevent or to stop the flow of hydraulic fluid to the second motor means when the pressure of hydraulic fluid within the first motor means is less than the predetermined level. The compaction panel and stuffer panel are thereby moved alternately in providing increased compaction to refuse within the storage body.
