Abstract:
Provided is an axial hydraulic pump including: a residual pressure regenerating circuit (30) which is a pipe line communicating with a top dead center side communication port (31) and a bottom dead center side communication port (32); cylinder ports (26-1 to 26-8) which are provided in the respective cylinder bores of the cylinder block (6) and are operated with the rotation of the cylinder block (6); and communication holes (41-1 to 41-8) which communicate with the top dead center side communication port (31) and the bottom dead center side communication port (32).
Abstract:
A compressor mounted on a vehicle-side mounting section by using through bolts. The area of that first mounting surface of the compressor at which the compressor is mounted on the vehicle-side mounting section is set greater than the area of a second mounting surface where seat surfaces for the heads of the through bolts are formed. Because both the mounting surfaces have different areas, vibration is suppressed when the compressor is mounted in place. Thus, the simple improvement can effectively reduce vibration when the compressor is mounted on the vehicle-side mounting section.

본 발명은 전기적 또는 기계적 오류에 의해 야기된 문제들의 경우 또는 첫 이용시에 각 동작을 계량하기 위한 수단이 구비된 냉각기 및 선형 컴프레서 뿐만 아니라, 유체 펌프(10)를 제어하는 방법 및 시스템에 관한 것이다. 본 발명의 제시에 따르면, 상기 유체 펌프(10)에는 피스톤-위치 센싱 어셈블리(11)가 구비되며, 상기 전자식 제어기(16)는 임팩트 신호를 검지함에 의해 각 실린더 내의 피스톤 변위를 모니터링한다. 상기 임팩트 신호는, 상기 피스톤의 상기 스트로크 말단과의 임팩트의 발생시 상기 센싱 어셈블리(11)에 의해 전달되며, 상기 전자식 제어기(16)는 피스톤 변위의 최대값을 저장하기 위해 상기 임팩트의 발생만큼 멀리 트리거 신호가 있는 때 상기 피스톤 변위 스트로크를 연속적으로 증가시킨다.
Abstract:
The present invention relates to a system and to a method of controlling a fluid pump (10), as well as to a linear compressor and a cooler provided with means to calibrate the respective functioning at the time of the first use or in cases of problems caused by electric or mechanical failures. According to the teachings of the present invention, the fluid pump (10) is provided with a piston-position sensing assembly (11), the electronic controller (16) monitoring the piston displacement within the respective cylinder by detecting an impact signal. The impact signal is transmitted by the sensing assembly (11) upon occurrence of a impact of the piston with the stroke end, the electronic controller (16) successively incrementing the piston displacement stroke upon a trigger signal as far as the occurrence of the impact to store a maximum value of piston displacement.
