Abstract

1,071,234. Hydraulic intensifiers. HONDA GIJUTSU KENKYUSHO. KABUSHIKI KAISHA. Feb. 23, 1965 [Feb. 25, 1964], No. 7854/65. Heading F1P. An hydraulic intensifier arrangement (Fig. not shown) comprises a main cylinder (1) in which is reciprocated a free piston (2) having two subsidiary cylinders formed therein, each of which co-operates with a stationary piston (4) provided in the adjacent end wall of the main cylinder (1), the arrangement being such that a pump (14) supplies pressurized fuel oil alternately to each end of the main cylinder to reciprocate the piston (2) whereby oil trapped in the opposite and smaller subsidiary cylinder (5) is intensified in pressure and flows past a non- return valve (30) to a fuel injector (8) of an I. C. engine. The oil is supplied alternately to each end of the main cylinder (1) by a continuously rotating rotary distributing valve (13) which causes alternate connection of lines (12) leading to the cylinder ends to the pump (14) or a sump (18). Assuming the left hand line (12) is connected to the pump (14), oil acts on the annular end of the free piston (2) to move it to the right. Movement to the right opens a port (9) in the piston and hence oil pressure acts over the entire left hand end surface of the piston (2) so that oil in the right hand subsidiary cylinder (5), after closure by the piston (2) of the right hand port (9), is pressurized and flows via a passage (6) in the piston (4) to the right hand non-return valve (30). Subsequent closure of the right hand line (23) by the continued movement of the piston (2) cushions the stroke. Each piston (4) has a rack (10) engageable by a pinion (11) rotatable to adjust the axial position of the piston. A pump (27) for supplying lubricant to the moving surfaces of the free piston (2) and the valve (13) is provided. The distributing valve may be of a reciprocating type.
