Abstract

1411702 Hydraulic jacks; reciprocating pumps DSO AVTOPROM 25 May 1973 [26 May 1972] 25304/73 Headings F1A and F1D A hydraulic jack has a pump which comprises an open ended cylinder 17, extending through a body 3, in which a piston 4 is reciprocated by a handle 1, one end of the cylinder being closed by a plug 10 which houses a non-return valve 8. When the piston is moved to the left liquid is drawn into the cylinder 17 through conduits 14, 13, 12, 11 and past the spring-loaded valve 8. When the piston is moved to the right the valve 8 closes and liquid is forced through a port 20 to extend the jack. Seals 5, 7 and 9 are provided.
