Hydraulic fluid reservoir and hydraulic system

A hydraulic fluid reservoir and hydraulic pump combination has at least one hydraulic fluid port and includes a container with a hollow body having a top and a conduit having a bottom within the container and a top above the bottom. The conduit has an opening adjacent to the bottom of the conduit. The opening is spaced apart below the top of the container. A closure member is releasably, sealingly connected to the top of the conduit. Hydraulic fluid can be added to the container via the conduit up to the level of the opening of the conduit. Addition of further hydraulic fluid fills the conduit to the top thereof and the conduit overflows if additional hydraulic fluid is added after the top of the conduit is reached by the fluid. Preferably the container has a main interior chamber and a smaller chamber which is adjacent to one of the side walls of the container. The smaller chamber is has a bottom opening near the bottom of the smaller chamber which communicates with the main interior chamber. Hydraulic fluid enters the smaller chamber through the opening and reaches the level of hydraulic fluid in the main interior chamber. Bubbles in the hydraulic fluid within the main interior chamber are isolated from the smaller chamber and accordingly do not impair the reading of the hydraulic fluid level by a photo detector.

Unmanned aerial vehicle system, parachute module, folding structure of parachute module, mold and parachute opening method

The invention discloses a parachute folding structure, a folding mold and a parachute module for unmanned aerial vehicle express box putting, and an unmanned aerial vehicle system for express box putting using the parachute module and a parachute opening method. The folding structure is folded back and forth from the center of the parachute along an upper folding line and a lower folding line in the outward radiation direction to form a concentric corrugated shape; the folding structure is formed by pressing through a mold; the parachute module comprises a bottom box, a middle ring and a folded parachute, and the middle ring is fixed to the center part and detachably connected to the lower portion of the unmanned aerial vehicle air-drop device through a parachute opening connecting piece. And the connection force between the parachute opening connecting piece and the air-drop device is enough to keep connection before the air-drop operation of the unmanned aerial vehicle and in the parachute opening process of the air-drop operation, and meanwhile, the unmanned aerial vehicle express box can be separated from the unmanned aerial vehicle and the parachute can be separated under the action of vertical pulling force after the parachute is completely pulled out. The parachute folding structure is simple and compact in structure, small in size after being folded, suitable for standardized and large-scale low-cost production, and smooth and reliable in parachute opening.
