Rubber seal is laid in off-load oil duct both sides, the energy heats that can be produced by off-load, further increases it in low temperature
The reliability worked under environment.
To achieve the above object, the utility model provides a kind of diesel engine steering pump, including：Low pressure oil pocket, it is located at
The front end of the diesel engine steering pump inner chamber, and correspondingly offer oil inlet；High-voltage oil cavity, it is located at the diesel engine steering pump inner chamber
Rear end, correspondence offers oil-out, and connected by oil duct with the oil-out；And first rubber seal and the second rubber
Glue seal, its use ethylene acrylate rubber, be arranged in the both sides of the oil duct, with seal the high-voltage oil cavity and
Low pressure oil pocket.
Preferably, in above-mentioned technical proposal, oil-out is located at the rear end of the diesel engine steering pump inner chamber.
Preferably, in above-mentioned technical proposal, the first rubber seal and the second rubber seal are O-ring seal.
Compared with prior art, the utility model has the advantages that：Rubber inside the diesel engine steering pump is close
Sealing material uses ethylene acrylate rubber, can keep reliable and stable work at low ambient temperatures.In addition, rubber seal cloth
Off-load oil duct both sides are located at, the energy heats that can be produced by off-load further increase what it worked at low ambient temperatures
Reliability.
