車装置を設けるにも、この装置が伝達する力が非常に大
きなものであるため装置は大寸法、大重量でかつ高価な
ものとなってしまうという問題がある。There are two major problems with high-pressure pumps, especially those that pump non-lubricating fluids such as water and exceed 1,000 atmospheres. A) difficulties in sealing the membrane members, which may cause leakage, and a change in the load on the tightening bolts, which shortens their useful life; and b) connects to the electric motor. In this case, the pump rotates at a high speed, and the valve and the membrane member perform a large number of reciprocating motions (strokes) in a short time, so that their service life is limited to several hundred hours. Even if a gear device is provided between the pump and the pump, there is a problem that the device is large in size, large in weight and expensive because the power transmitted by the device is very large.
本発明は、駆動モータとポンプの間に伝達装置を用い

の生じないように構成する。To make this solution effective, a small reduction gear is used between the drive motor and the pump. In order to improve the sealing structure of the membrane member and prolong the service life of the tightening bolt, a circular annular portion and a leak reservoir recess are provided on the body member which abuts against the membrane member and tightens them, and is sealed. Also, when high pressure is applied to one of the chambers, low pressure is applied to the other of the chambers, so that the load on the tightening bolt is always increased because those chambers are arranged in the axial direction. The load is uniform and the load is not changed.

伸びの好ましい均衡をはかるようにしている。Another important construction feature according to the present invention is shown in FIG. That is, the membrane member 58 is a bolt (with a nut or head 66) between the radially flat surfaces of the body members A and B or C and D forming the first chamber 135,235 or the second chamber 137,237. 4 is held tight. Radially outward of the first and second chambers, the end faces of body members A, B, C and D are planar, and membrane member 58 is a flat plate member having parallel axial end faces. Also, the flat end faces of the body member are parallel to each other. Displaced slightly radially outward from the first and second chambers, leak reservoir recesses 61, 62 are formed in the body member in the form of circular depressions from the flat end surface of the body member. Have been. These recesses 61,6
2 is connected to the leak outlet. An important sealing arrangement is provided between the chambers 135,235,137,237 and the recesses 61,62. These sealing components are circular annuli of the body member, which engage corresponding parts of the axial end faces of the membrane member, and the flat surfaces of the annuli are bolts 4 (and their holdings). Since they are mutually pressed (tightened) by means or nuts 66), the membrane member is sealed. Along the sealing arrangement, if a leak escapes, it enters the leak reservoir recesses 61,62. The radially outer end face of the membrane member 58 has a recess 61,
62 radially outward portion and adjacent body members A, B, C, D
And seals the recesses 61, 62 radially outward and provides a good balance of compressive stress and bolt elongation on portions of the membrane member.

延命される。The important point according to the invention is that, reversibly, the chamber 135,
When the high pressure is applied to 137, the chambers 235 and 237 are configured to be applied with low pressure. According to the invention, it is preferred that the operation of the control valve is very perfect and there is no time lag when switching the pressure from the chambers 135, 137 to the chambers 235, 237 and vice versa. According to this configuration, the stress generated in the bolt 4 provided with the (holding means 66 such as a nut) due to the high pressure in each chamber during the discharge stroke can always be made uniform. As a result, a change to a low pressure is prevented, and a uniform internal elongation stress is always applied to the bolt 4, so that a change in load and stress applied to the bolt is prevented, and a service life can be extended. Furthermore, the compressive stresses in the sealing components of the membrane member and the body member are also very substantially uniform, preventing this change in the compressive stress, and thus also providing a reliable service life of the membrane member and the body member. Life prolonged.
