Abstract

The invention relates to a plunger pump and engineering machinery. The plunger pump comprises a shell (2), a cylinder block (5), plungers (8) and an end cover (6), wherein the cylinder block (5) is arranged in the shell (2) and comprises a plurality of plunger holes formed in the circumferential direction of the shell (2); the plungers (8) are arranged in one-to-one correspondence with the plungerholes and can do reciprocating motion in the corresponding plunger holes; one end of the shell (2) is covered with the end cover (6); the end cover (6) is provided with a pore channel communicating with the cylinder block (5) and a valve arranged in the pore channel. The end cover is provided with the pore channel communicating with the cylinder block (5). The valve is arranged in the pore channel. The problems that a plunger pump is complex in structure and large in size in the prior art are improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a plunger pump and construction machinery. Background technique [0002] A related art plunger pump includes a housing and a pump body provided in the housing. The pump body includes a cylinder with a plunger hole, a rotating shaft for driving the cylinder to rotate, a reciprocating plunger set in the plunger hole, and one end of the cylinder obliquely relative to the axial direction of the cylinder. The swash plate and the elastic part are used to push the plunger towards the swash plate. During the rotation of the cylinder relative to the swash plate, the elastic part can push the plunger towards the outside of the plunger hole so that the plunger hole is drawn out. The hydraulic fluid is sucked, and during the rotation of the cylinder relative to the swash plate, the swash plate can push the plunger toward the inside of the plunger hole to push out the hydraulic fluid in...
