油圧ポンプ及び油圧バルブを一体組付けたした油
圧回路ユニツトに関する。[Detailed description of the invention] [Industrial application field] This invention applies to the components necessary for the hydraulic circuit configuration, excluding the prime mover and actuator, the oil tank,
This invention relates to a hydraulic circuit unit in which a hydraulic pump and a hydraulic valve are integrally assembled.

Usually, each component necessary for configuring a hydraulic circuit is attached to a desired device at a desired position and connected through piping or the like to form a required hydraulic circuit. Therefore, methods have been adopted to integrate these components as much as possible into a hydraulic unit. For example, a hydraulic cylinder device in which a hydraulic valve with a servo valve is attached to a hydraulic cylinder is common.

成されているものが開示されている。 As another example, Japanese Utility Model Publication No. 53-46580 describes a hydraulic device that is driven by power from a prime mover and that drives a hydraulic cylinder that raises and lowers the pre-processing section of a combine harvester, and that is mounted externally in an oil tank. A device is disclosed that is composed of a hydraulic pump and an internal control valve.
上記の油圧装置はコントロールバルブが油タン

In the above hydraulic system, the control valve is built inside the oil tank, but the hydraulic pump is mounted outside the oil tank, so the size of the hydraulic pump and the oil tank, that is, the external shape and dimensions, are different. In this case, a large dead space is created around the area where the hydraulic pump is installed, and when the entire device is assembled into the aircraft, a larger space than necessary is required, which poses the problem of deteriorating the efficiency of space utilization. Ta.
本考案が解決しようとする技術的課題は、油タ
ンク、油圧ポンプ及び油圧バルブの三者を周辺の
デツドスペースが極めて少なくなるように一体組
付けしてユニツト化する点にある。 The technical problem to be solved by the present invention is to assemble an oil tank, a hydraulic pump, and a hydraulic valve into a unit so that the surrounding dead space is extremely reduced.
上記技術的課題を解決するために講じた技術的
手段は、貯油タンクの側壁を部分的に凹入させて

The technical means taken to solve the above technical problem is to partially recess the side wall of the oil storage tank to form a recess, and insert a hydraulic pump and a hydraulic valve into the recess. At the same time, the oil suction port of the hydraulic pump and the oil drain port of the hydraulic valve are communicated into the oil tank through the both side walls of each of the recessed portions, and the oil supply port of the hydraulic pump and the oil pressure valve are connected to each other. It is to communicate with the oil receiving port of the valve.
上記技術的手段は、次のように作用する。 The above technical means works as follows.
貯油タンク、油圧ポンプ及び油圧バルブの三者
の内最も大きいスペースが要求される貯油タンク
を中心部材とし、上記の通り、貯油タンクに形成
した凹入部内に、ポンプとバルブとを入り込ませ

流体の連通を貯油タンクの両凹入部の側壁を介し
て連通してあるから、これらの一体化物は、油圧
流体の連通路がタンク外部の外側に露出しない状
態で外周に凹凸が少なくデツドスペースの極めて
少ないユニツトに構成することができる。 The oil storage tank, which requires the largest space among the three, the oil storage tank, the hydraulic pump, and the hydraulic valve, is the central member, and the pump and valve are inserted and fixed in the recess formed in the oil storage tank as described above. At the same time, since the hydraulic fluid communication between each of the three parts is communicated through the side walls of both recessed parts of the oil storage tank, the integrated structure allows the hydraulic fluid communication path to be exposed to the outside of the tank. In this case, the unit can be constructed with few irregularities on the outer periphery and an extremely small amount of dead space.
従つて、本考案の効果を奏する。 Therefore, the effects of the present invention are achieved.
前記の三者の一体化物は流体連通路が外部に露
出しない状態で外周に凹凸が少なくデツドスペー

い、すなわち油漏洩の可能性の極めて少ないかつ
連結簡単容易なものとするとができ、全体として
信頼性の向上と構造簡単化できるに至つた。 Since the above-mentioned three-piece integrated unit can be constructed into a unit with minimal irregularities on the outer periphery and extremely small dead space without exposing the fluid communication passage to the outside, this integrated unit can be placed in a close position where it is easy to obtain power from the engine. It has now become possible to install it directly with extremely little dead space.
A compact mounting configuration that is extremely efficient in terms of space utilization has been achieved. In addition, the fluid communication path is sealed within this unit, and it is only necessary to form a communication path between the hydraulic valve and the required hydraulically driven devices such as the hydraulic cylinder, and there are fewer connection points, which means there is less possibility of oil leakage. As a result, the connection can be made simple and easy, and the overall reliability can be improved and the structure can be simplified.
