摘要： In a cooling package for a construction machine, where a cooler (16) from among coolers (15, 16) is disposed separately from an engine (10) and the separately provided cooler (16) includes a screen (19), a lid (30, 50) for covering the screen (19) from above is provided on an upper face of the construction machine independently of a side door (21A, 21B) provided on a side face of the construction machine for covering the cooler (15, 16) from forwardly and an engine hood (22) provided on the upper face of the construction machine for covering the engine (10) and the cooler (15) provided for the engine (10) from above so that, even when the location forwardly of the cooler (16) disposed separately from the engine (10) is occupied by some other apparatus, the screen (19) can be removed or mounted without being disturbed by the apparatus.

摘要： A main poppet body of a logic valve receives inlet pressure at first and second ends. A flow-restricting orifice between the first and second ends produces a differential pressure between the two ends when inlet fluid is permitted to flow from the second end. The main poppet body is normally resiliently seated against a seat. A pilot poppet body, movable in the main poppet body, seats against a seat in the main poppet body. The pilot poppet body, when sealed to its seat, seals the fluid at the second end of the main poppet body from flowing. Thus, equal pressures exist at opposed ends of the main poppet body, and the main poppet body remains in its sealing position. An external source of controllable pilot pressure acts on the pilot poppet body to unseal it from its seat. This permits a flow of inlet fluid from the second end of the main poppet body, and produces a pressure reduction at the second end. The differential pressure between the first and second ends of the main poppet body tends to move the main poppet body out of its sealing position, and consequently to permit an inlet flow past the seat of the main poppet body. This inlet fluid flows to a drain. The position of the main poppet body varies in substantially linear relationship to the pilot pressure applied to the pilot poppet body.
